Vibration Analysis and Control

Vibration Analysis and Control

Vibration Analysis and Control Vibration analysis and control are crucial aspects of engineering andindustrial maintenance. Vibration can cause significant damage to machinery, leading to increased maintenance costs and downtime. Therefore, it is essential to understand the causes of vibration and implement effective control measures to mitigate its impact. In this response, we will explore the importance of vibration analysis and control, the methods and tools used for analysis, and the strategies for implementing control measures. Vibration analysis is the process ofmonitoring and analyzing the vibration levels of machinery and equipment toidentify any irregularities or potential issues. This is typically done using specialized equipment such as accelerometers and vibration meters, which measure the amplitude, frequency, and intensity of vibrations. By analyzing this data, engineers can identify the root causes of vibration, such as unbalanced components, misalignments, or mechanical wear, and take corrective actions to address these issues. One of the key benefits of vibration analysis is its ability to detect potential faults at an early stage, allowing maintenance teams to take proactive measures to prevent machinery breakdowns. This can significantly reduce downtime and maintenance costs, as well as improve overall operational efficiency. Additionally, vibration analysis can help identify the underlying causes of vibration, allowing engineers to implement targeted control measures to address these issues. There are various methods and tools used for vibration analysis, including time waveform analysis, frequency spectrum analysis, and phase analysis. Time waveform analysis involves capturing and analyzing the raw vibration signalto identify any irregularities or patterns. Frequency spectrum analysis, on the other hand, involves converting the time waveform data into frequency domain to identify the dominant frequencies and their harmonics. Phase analysis is used to assess the relative timing of different vibration signals, which can provide insights into the root causes of vibration. In addition to these methods, advanced techniques such as modal analysis and operating deflection shape (ODS) analysis are used to understand the dynamic behavior of machinery and identify potential resonance issues. Modal analysis helps engineers identify the natural frequencies and mode shapes of a system, while ODS analysis is used to visualizethe vibration patterns of machinery under operating conditions. These techniques provide valuable insights into the structural dynamics of machinery, allowing engineers to implement targeted control measures to mitigate vibration issues. Once the root causes of vibration have been identified through analysis, it is essential to implement effective control measures to address these issues. This may involve correcting misalignments, balancing rotating components, replacing worn bearings, or implementing damping measures to reduce vibration amplitudes. In some cases, structural modifications may be required to address resonance issues or improve the overall dynamic behavior of machinery. It is important to notethat vibration control measures should be implemented in a systematic and holistic manner, considering the specific characteristics of the machinery and the operational environment. This may involve collaboration between engineering, maintenance, and operational teams to develop and implement effective control strategies. Furthermore, ongoing monitoring and analysis are essential to ensure the effectiveness of these control measures and identify any new vibration issues that may arise. In conclusion, vibration analysis and control are essential aspects of engineering and industrial maintenance. By monitoring and analyzing vibration levels, engineers can identify potential faults at an early stage and implement targeted control measures to mitigate their impact. This not only reduces maintenance costs and downtime but also improves overall operational efficiency. With the use of advanced analysis methods and tools, as well as a systematic approach to implementing control measures, engineers can effectively manage vibration issues and ensure the reliable operation of machinery and equipment.。

State-of-the-art report of bridge health monitoring AbstractThe damage diagnosis and healthmonitoring of bridge structures are active areas of research in recent years. Comparing with the aerospace engineering and mechanical engineering, civil engineering has the specialities of its own in practice. For example, because bridges, as well as most civil engineering structures, are large in size, and have quite lownatural frequencies and vibration levels, at low amplitudes, the dynamic responses of bridge structure are substantially affected by the nonstructural components, unforeseen environmental conditions, and changes in these components can easily to be confused with structural damage.All these give the damage assessment of complex structures such as bridges a still challenging task for bridge engineers. This paper firstly presents the definition of structural healthmonitoring system and its components. Then, the focus of the discussion is placed on the following sections:①the laboratory and field testing research on the damage assessment;②analytical developments of damage detectionmethods, including (a) signature analysis and pattern recognition approaches, (b) model updating and system identification approaches, (c) neural networks approaches; and③sensors and their optimum placements. The predominance and shortcomings of each method are compared and analyzed. Recent examples of implementation of structural health monitoring and damage identification are summarized in this paper. The key problem of bridge healthmonitoring is damage automatic detection and diagnosis, and it is the most difficult problem. Lastly, research and development needs are addressed.1 IntroductionDue to a wide variety of unforeseen conditions and circumstance, it will never be possible or practical to design and build a structure that has a zero percent probability of failure. Structural aging, environmental conditions, and reuse are examples of circumstances that could affect the reliability and the life of a structure. There are needs of periodic inspections to detect deterioration resulting from normal operation and environmental attack or inspections following extreme events, such as strong-motion earthquakes or hurricanes. To quantify these system performance measures requires some means to monitor and evaluate the integrity of civil structureswhile in service. Since the Aloha Boeing 737 accident that occurred on April28, 1988, such interest has fostered research in the areas of structural health monitoring and non-destructive damage detection in recent years.According to Housner, et al. (1997), structural healthmonitoring is defined as“the use ofin-situ,non-destructive sensing and analysis of structural characteristics, including the structural response, for detecting changes that may indicate damage or degradation”[1]. This definition also identifies the weakness. While researchers have attempted the integration of NDEwith healthmonitoring, the focus has been on data collection, not evaluation. What is needed is an efficient method to collect data from a structure in-service and process the data to evaluate key performance measures, such as serviceability, reliability, and durability. So, the definition byHousner, et al.(1997)should be modified and the structural health monitoring may be defined as“the use ofin-situ,nondestructive sensing and analysis of structural characteristics, including the structural response, for the purpose of identifying if damage has occurred, determining the location of damage, estimatingthe severityof damage and evaluatingthe consequences of damage on the structures”(Fig.1). In general, a structural health monitoring system has the potential to provide both damage detection and condition assessment of a structure.Assessing the structural conditionwithout removingthe individual structural components is known as nondestructive evaluation (NDE) or nondestructive inspection. NDE techniques include those involving acoustics, dye penetrating,eddy current, emission spectroscopy, fiber-optic sensors, fiber-scope, hardness testing, isotope, leak testing, optics, magnetic particles, magnetic perturbation, X-ray, noise measurements, pattern recognition, pulse-echo, ra-diography, and visual inspection, etc. Mostof these techniques have been used successfullyto detect location of certain elements, cracks orweld defects, corrosion/erosion, and so on. The FederalHighwayAdministration(FHWA, USA)was sponsoring a large program of research and development in new technologies for the nondestructive evaluation of highway bridges. One of the two main objectives of the program is to develop newtools and techniques to solve specific problems. The other is to develop technologies for the quantitative assessment of the condition of bridges in support of bridge management and to investigate howbest to incorporate quantitative condition information into bridge management systems. They hoped to develop technologies to quickly, efficiently, and quantitatively measure global bridge parameters, such as flexibility and load-carrying capacity. Obviously, a combination of several NDEtechniques may be used to help assess the condition of the system. They are very important to obtain the data-base for the bridge evaluation.But it is beyond the scope of this review report to get into details of local NDE.Health monitoring techniques may be classified as global and local. Global attempts to simultaneously assess the condition of the whole structure whereas local methods focus NDE tools on specific structural components. Clearly, two approaches are complementaryto eachother. All such available informationmaybe combined and analyzed by experts to assess the damage or safety state of the structure.Structural health monitoring research can be categorized into the following four levels: (I) detecting the existence of damage, (II) findingthe location of damage, (III) estimatingthe extentof damage, and (IV) predictingthe remaining fatigue life. The performance of tasks of Level (III) requires refined structural models and analyses, local physical examination, and/or traditional NDE techniques. To performtasks ofLevel (IV) requires material constitutive information on a local level, materials aging studies, damage mechanics, and high-performance computing. With improved instrumentation and understanding of dynamics of complex structures, health monitoring and damage assessment of civil engineering structures has become more practical in systematic inspection and evaluation of these structures during the past two decades.Most structural health monitoringmethods under current investigation focus on using dynamic responses to detect and locate damage because they are global methods that can provide rapid inspection of large structural systems.These dynamics-based methods can be divided into fourgroups:①spatial-domain methods,②modal-domain methods,③time-domain methods, and④frequency- domain methods. Spatial-domain methods use changes of mass, damping, and stiffness matrices to detect and locate damage. Modal-domain methods use changes of natural frequencies, modal damping ratios, andmode shapesto detect damage. In the frequency domain method, modal quantities such as natural frequencies, damping ratio, and model shapes are identified.The reverse dynamic systemof spectral analysis and the generalized frequency response function estimated fromthe nonlinear auto-regressive moving average (NARMA) model were applied in nonlinear system identification. In time domainmethod, systemparameterswere determined fromthe observational data sampled in time. It is necessaryto identifythe time variation of systemdynamic characteristics fromtime domain approach if the properties of structural systemchangewith time under the external loading condition. Moreover, one can use model-independent methods or model-referenced methods to perform damage detection using dynamic responses presented in any of the four domains. Literature shows that model independent methods can detect the existence of damage without much computational efforts, butthey are not accurate in locating damage. On the otherhand, model-referencedmethods are generally more accurate in locating damage and require fewer sensors than model-independent techniques, but they require appropriate structural models and significant computational efforts. Although time-domain methods use original time-domain datameasured using conventional vibrationmeasurement equipment, theyrequire certain structural information and massive computation and are case sensitive. Furthermore, frequency- and modal-domain methods use transformed data,which contain errors and noise due totransformation.Moreover, themodeling and updatingofmass and stiffnessmatrices in spatial-domain methods are problematic and difficult to be accurate. There are strong developmenttrends that two or three methods are combined together to detect and assess structural damages.For example, several researchers combined data of static and modal tests to assess damages. The combination could remove the weakness of each method and check each other. It suits the complexity of damage detection.Structural health monitoring is also an active area of research in aerospace engineering, but there are significant differences among the aerospace engineering, mechanical engineering, and civil engineering in practice. For example,because bridges, as well as most civil engineering structures, are large in size, and have quite lownatural frequencies and vibration levels, at lowamplitudes, the dynamic responses of bridge structure are substantially affected by the non-structural components, and changes in these components can easily to be confused with structural damage. Moreover,the level of modeling uncertainties in reinforced concrete bridges can be much greater than the single beam or a space truss. All these give the damage assessment of complex structures such as bridges a still challenging task for bridge engineers. Recent examples of research and implementation of structural health monitoring and damage assessment are summarized in the following sections.2 Laboratory and field testing researchIn general, there are two kinds of bridge testing methods, static testing and dynamic testing. The dynamic testing includes ambient vibration testing and forcedvibration testing. In ambient vibration testing, the input excitation is not under the control. The loading could be either micro-tremors, wind, waves, vehicle or pedestrian traffic or any other service loading. The increasing popularity of this method is probably due to the convenience of measuring the vibrationresponse while the bridge is under in-service and also due to the increasing availability of robust data acquisition and storage systems. Since the input is unknown, certain assumptions have to be made. Forced vibration testing involves application of input excitation of known force level at known frequencies. The excitation manners include electro-hydraulic vibrators, force hammers, vehicle impact, etc. The static testing in the laboratory may be conducted by actuators, and by standard vehicles in the field-testing.we can distinguish that①the models in the laboratory are mainly beams, columns, truss and/or frame structures, and the location and severity of damage in the models are determined in advance;②the testing has demonstrated lots of performances of damage structures;③the field-testing and damage assessmentof real bridges are more complicated than the models in the laboratory;④the correlation between the damage indicator and damage type,location, and extentwill still be improved.3Analytical developmentThe bridge damage diagnosis and health monitoring are both concerned with two fundamental criteria of the bridges, namely, the physical condition and the structural function. In terms of mechanics or dynamics, these fundamental criteria can be treated as mathematical models, such as response models, modal models and physical models.Instead of taking measurements directly to assess bridge condition, the bridge damage diagnosis and monitoring systemevaluate these conditions indirectly by using mathematical models. The damage diagnosis and health monitoring are active areas of research in recentyears. For example, numerous papers on these topics appear in the proceedings of Inter-national Modal Analysis Conferences (IMAC) each year, in the proceedings of International Workshop on Structural HealthMonitoring (once of two year, at Standford University), in the proceedings of European Conference on Smart materials and Structures and European Conference on Structural Damage AssessmentUsing Advanced Signal Processing Procedures, in the proceedings ofWorld Conferences of Earthquake Engineering, and in the proceedings of International Workshop on Structural Control, etc.. There are several review papers to be referenced, for examples,Housner, et al. (1997)provided an extensive summary ofthe state of the art in control and health monitoring of civil engineering structures[1].Salawu (1997)discussed and reviewed the use of natural frequency as a diagnostic parameter in structural assessment procedures using vibration monitoring.Doebling, Farrar, et al. (1998)presented a through review of the damage detection methods by examining changes in dynamic properties.Zou, TongandSteven (2000)summarized the methods of vibration-based damage and health monitoring for composite structures, especially in delamination modeling techniques and delamination detection.4Sensors and optimum placementOne of the problems facing structural health monitoring is that very little is known about the actual stress and strains in a structure under external excitations. For example, the standard earthquake recordings are made ofmotions of the floors of the structure and no recordings are made of the actual stresses and strains in structural members. There is a need for special sensors to determine the actual performance of structural members. Structural health monitoring requires integrated sensor functionality to measure changes in external environmental conditions, signal processing functionality to acquire, process, and combine multi-sensor and multi-measured information. Individual sensors and instrumented sensor systems are then required to provide such multiplexed information.FuandMoosa (2000)proposed probabilistic advancing cross-diagnosis method to diagnosis-decision making for structural health monitoring. It was experimented in the laboratory respectively using a coherent laser radar system and a CCD high-resolution camera. Results showed that this method was promising for field application. Another new idea is thatneural networktechniques are used to place sensors. For example,WordenandBurrows (2001)used the neural network and methods of combinatorial optimization to locate and classify faults.The static and dynamic data are collected from all kinds of sensorswhich are installed on the measured structures.And these datawill be processed and usable informationwill be extracted. So the sensitivity, accuracy, and locations,etc. of sensors are very important for the damage detections. The more information are obtained, the damage identification will be conducted more easily, but the price should be considered. That’s why the sensors are determined in an optimal ornearoptimal distribution. In aword, the theory and validation ofoptimumsensor locationswill still being developed.5 Examples of health monitoring implementationIn order for the technology to advance sufficiently to become an operational system for the maintenance and safety of civil structures, it is of paramount importance that new analytical developments are ultimately verified with appropriate data obtained frommonitoring systems, which have been implemented on civil structures, such as bridges.Mufti (2001)summarized the applications of SHM of Canadian bridge engineering, including fibre-reinforced polymers sensors, remote monitoring, intelligent processing, practical applications in bridge engineering, and technology utilization. Further study and applications are still being conducted now.FujinoandAbe(2001)introduced the research and development of SHMsystems at the Bridge and Structural Lab of the University of Tokyo. They also presented the ambient vibration based approaches forLaser DopplerVibrometer (LDV) and the applications in the long-span suspension bridges.The extraction of the measured data is very hard work because it is hard to separate changes in vibration signature duo to damage form changes, normal usage, changes in boundary conditions, or the release of the connection joints.Newbridges offer opportunities for developing complete structural health monitoring systems for bridge inspection and co ndition evaluation from“cradle to grave”of the bridges. Existing bridges provide challenges for applying state-of-the-art in structural health monitoring technologies to determine the current conditions of the structural element,connections and systems, to formulate model for estimating the rate of degradation, and to predict the existing and the future capacities of the structural components and systems. Advanced health monitoring systems may lead to better understanding of structural behavior and significant improvements of design, as well as the reduction of the structural inspection requirements. Great benefits due to the introduction of SHM are being accepted by owners, managers, bridge engineers, etc..6 Research and development needsMost damage detection theories and practices are formulated based on the following assumption: that failure or deterioration would primarily affect the stiffness and therefore affect the modal characteristics of the dynamic response of the structure. This is seldom true in practice, because①Traditional modal parameters (natural frequency, damping ratio and mode shapes, etc.) are not sensitive enough to identifyand locate damage. The estimation methods usually assume that structures are linear and proportional damping systems.②Most currently used damage indices depend on the severity of the damage, which is impractical in the field. Most civil engineering structures, such as highway bridges, have redundancy in design and large in size with low natural frequencies. Any damage index should consider these factors.③Scaledmodelingtechniques are used in currentbridge damage detection. Asingle beam/girder models cannot simulate the true behavior of a real bridge. Similitude laws for dynamic simulation and testing should be considered.④Manymethods usually use the undamaged structural modal parameters as the baseline comparedwith the damaged information. This will result in the need of a large data storage capacity for complex structures. But in practice,there are majority of existing structures for which baseline modal responses are not available. Only one developed method(StubbsandKim (1996)), which tried to quantify damagewithout using a baseline, may be a solution to this difficulty. There is a lot of researchwork to do in this direction.⑤Seldommethods have the ability to distinguish the type of damages on bridge structures. To establish the direct relationship between the various damage patterns and the changes of vibrational signatures is not a simple work.Health monitoring requires clearly defined performance criteria, a set of corresponding condition indicators and global and local damage and deterioration indices, which should help diagnose reasons for changes in condition indicators. It is implausible to expect that damage can be reliably detected or tracked by using a single damage index. We note that many additional localized damage indiceswhich relate to highly localized properties ofmaterials or the circumstances may indicate a susceptibility of deterioration such as the presence of corrosive environments around reinforcing steel in concrete, should be also integrated into the health monitoring systems.There is now a considerable research and development effort in academia, industry, and management department regarding global healthmonitoring for civil engineering structures. Several commercial structural monitoring systems currently exist, but further development is needed in commercialization of the technology. We must realize that damage detection and health monitoring for bridge structures by means of vibration signature analysis is a very difficult task. Itcontains several necessary steps, including defining indicators on variations of structural physical condition, dynamic testing to extract such indication parameters,defining the type of damages and remaining capacity or life of the structure, relating the parameters to the defined damage/aging. Unfortunately, to date, no one has accomplished the above steps. There is a lot of work to do in future.桥梁健康监测应用与研究现状摘要桥梁损伤诊断与健康监测是近年来国际上的研究热点,在实践方面,土木工程和航空航天工程、机械工程有明显的差别,比如桥梁结构以及其他大多数土木结构,尺寸大、质量重,具有较低的自然频率和振动水平,桥梁结构的动力响应极容易受到不可预见的环境状态、非结构构件等的影响,这些变化往往被误解为结构的损伤,这使得桥梁这类复杂结构的损伤评估具有极大的挑战性.本文首先给出了结构健康监测系统的定义和基本构成,然后集中回顾和分析了如下几个方面的问题:①损伤评估的室内实验和现场测试;②损伤检测方法的发展,包括:(a)动力指纹分析和模式识别方法, (b)模型修正和系统识别方法, (c)神经网络方法;③传感器及其优化布置等,并比较和分析了各自方法的优点和不足.文中还总结了健康监测和损伤识别在桥梁工程中的应用,指出桥梁健康监测的关键问题在于损伤的自动检测和诊断,这也是困难的问题;最后展望了桥梁健康监测系统的研究和发展方向.关键词:健康监测系统;损伤检测;状态评估;模型修正;系统识别;传感器优化布置;神经网络方法;桥梁结构1概述由于不可预见的各种条件和情况下,设计和建造一个结构将永远不可能或无实践操作性,它有一个失败的概率百分之零。

(Standard vibration analysis viewer shown in image)Basic Solution ArchitectureFIGURE 2.The typical InsightCM system architecture connects wired and wireless sensors from multiple plant assets to IT networks, enterprise digital technology, and subject matter experts.InsightCM BenefitsImprove Productivity with Remote DiagnosticsInsightCM helps analysts and plant personnel shift focus away from manual data collection, freeing up time for more value-add activities such as data analysis, maintenance planning, and plant operations. Included features let you:▪L og in to the InsightCM server from any web browser with network access and perform real time analysis ▪C over more assets across your fleet with your existing team▪G et to analysis faster with data screening, alarming, and multi-sensor analysis toolsMinimize Change by Connecting to Existing Enterprise Software and IPInsightCM is the most open condition-monitoring application software on the market giving you the freedomto use the tools you need to meet your goals. Connect InsightCM data with:▪T he OSIsoft PI System™▪B lack & Veatch Asset360®▪G P Strategies EtaPRO▪A vantis® PRiSM▪M icrosoft Azure IoT Hub ▪I BM Maximo®▪M icrosoft Excel ▪A VEVA eDNA ▪P TC ThingWorxManage Any Sensor with One Software ToolInsightCM supports a variety of sensor technologies to help catch multiple failure modes and crosscheck diagnoses for greater confidence. Supported measurement technologies include:▪V ibration (accelerometers, proximity probes, temperature, 4-20 mA and ±30 V static sensors)▪M otor-current signature analysis (MCSA) (potential transformers, current transformers)▪T hermography (infrared cameras)▪G enerator Field Monitoring (includes shaft voltage and current as well as Rotor Flux Monitoring in onesystem)▪A vailable for hydroelectric, nuclear, and compound generators▪E MI Monitoring ( Monitoring Generators, motors, circuit breakers, and transformers for electrical defects) ▪P artial Discharge Monitoring: The Partial Discharge (PD) measurement consists on a 2D histogram of PD Pulses known as PD Pattern or PRPD (Phase Resolved Partial Discharge) Pattern. All trending parameters are available in Insight CM▪B rush Condition Monitoring; Carbon Brush Length, Temperature and Vibration can be imported to Insight CM for trend analysisFocus on Relevant DataInsightCM systems can continuously (24x7) acquire and screen data from connected analog sensors. This architecture helps detect alarm limit excursions and operating-state changes in near real time, helping analysts focus on data with value, rather than parsing through numerous data sets collected during monthly routes.Meet Your Security NeedsOnly authenticated hardware and verified users have access to InsightCM. Secure remote password protocol provides authentication between asset monitoring systems and InsightCM. IT system administrators can specify a disconnection interval to force the asset-monitoring nodes to disconnect from the server and reauthenticate themselves. Access to InsightCM is role-based and gives IT system administrators the ability to restrict access to certain functionality to qualified users. These roles and user authentication can be linked to an existing corporate Lightweight Directory Access Protocol/Active Directory group for centralized role management. User activity between the client browser and InsightCM can be further secured using Secure Sockets Layer encryption.Prepare for the Future with an Open, Customizable SystemThe Software Development Kit (SDK) for InsightCM helps customize the solution and prepare your business for almost any future needs, including new sensor technologies, communication protocols, and analysis methods. Add your custom analysis IP, connect to third-party hardware, or save to any file format using the SDK. Cutsforth offers a worldwide partner network that can customize InsightCM installations to fit specific needs and adapt them to future expansion.Monitoring Devices for Any AssetFor Critical Assets with Protection SystemsContinuous Monitoring Systems connect directly to existing protection systems through the buffered analog outputs. This pass-through approach lets maintenance teams add modern, connected, online monitoring systems to legacy hardware with limited communication and analysis capability. Additionally, the buffered analog outputs serve as the security firewall to let plants connect data to standard, business IT networks, without a data diode, rather than the highly protected control networks.FIGURE 3.Cutsforth Continuous Monitoring Systems connect to existing protection systems through the buffered analog outputs to add modern online monitoring analysis to legacy, or secured, protection systems.Continuous Monitoring System Key FeaturesContinuous Monitoring Systems are built on a rugged measurement system (CompactRIO) and feature four or eight slots for sensor-specific modules. High-speed voltage input modules are used for connection to the output from the buffered analog output on the protection rack.Note: Module configurations for Continuous Monitoring Systems are specific to the asset and InsightCM toolkits. Please contact your Cutsforth sales representative for configuration assistance.FIGURE 4.Continuous Monitoring Systems (eight-slot option shown) are built on CompactRIO systems; proven technologywith more than 15 years of deployment in a variety of heavy industries.Hardware Specifications▪D ual 10/100/1000 ENET Ports▪U p to Quad-Core Intel Atom Processor ▪P assively cooled, -40 °C to 70 °C ▪S SD for Temporary Local Storage▪I nsightCM Monitoring System Firmware ▪L inux Real-Time OSIntelligent Data Triggering with Continuous Monitoring SystemsContinuous Monitoring Systems intelligently capture data based on a configuration you specify, which reduces overall data volume and provides a way to isolate important asset events. Use the following events to trigger a data capture:▪T ime—Data is captured in user-configurable time intervals such as once an hour, once a day, three times a day, and so on. Choose when to capture the features calculated (less data), the full waveform (more data), or both.▪C hange in engineering units (delta EU)—Data is captured when a calculated feature changes by the set delta value with respect to the initial measured value. Once the trigger condition is met, the trigger resets from the latest value but retains the same delta limit. This feature is most often used for ramp-ups and coast-downs, during which data recordings at periodic rotational speeds are desired; for example, recording a 4 swaveform every 50 rpm during ramp-up.▪A larm limits—Data is captured when a measured feature crosses a preset limit. You must acknowledge alarms before retriggering.▪F orce trigger—You can request a real-time reading using the force trigger option in the action menu for any device. This feature is good for troubleshooting sensor connections, spot-checking an asset, orinvestigating the current state before acknowledging an alarm.Burst ModeWith burst mode, you can preset a time to collect data at higher acquisition rates (up to 102.4 kS/s per channel) to analyze assets with slow rotational speed. Continuous Monitoring Systems revert to the lower set acquisition rate for feature calculation, trigger, and alarm screening.StreamsStreams are useful for grouping transient event data—such as run-ups or coast-downs—to ease analysis. During streams, data is generally sent more frequently, providing more context on how the asset is performing during critical periods. These events can be observed in real time or after the fact.Spectral LimitsScreen data as it arrives on the server with spectral limits you set using a graphical tool to mask off frequency by amplitude across the spectrum. This tool is helpful to quickly isolate which machines may be experiencing signs of early stage bearing wear.Security Implications with One-Way Measurement from Protection SystemThe only connection path from the protection system to the hardware is the one-way, analog signal connection from the buffered AOs on the protection system. The Continuous Monitoring System has no connection or path to send a signal back to the protection system. The one-way, analog-input topology provides no method for communication to, or control of, the protection system, which may assist with cyber-security policies when needed.FIGURE 5.Continuous monitoring systems for assets with protection systems typically install in the same rack as the protection system and connect through front or back-panel connectors to the buffered-analog outputs.For Dynamic Assets that Need 24x7 MonitoringContinuous monitoring systems cover a wide variety of dynamic and process sensors to monitor assets with multiple operating states or problematic assets with a higher propensity of failure between service intervals. The advanced acquisition modes referenced above (intelligent data triggering and burst mode) are available for continuous monitoring systems for dynamic assets.FIGURE 6.Multiple sensor module options help tailor the Continuous Monitoring System to specific asset sensor needs. Please contact your Cutsforth sales representative for assistance in configuring an InsightCM Continuous Monitoring Device.Supported Sensor InputsYou can connect Continuous Monitoring Systems to virtually any sensor technology and use them with rotational, electrical, static, and process asset types. The devices support the following sensor types out of the box:▪A ccelerometer with or without Integrated Electronic Piezoelectric (IEPE) (vibration)▪T achometer (speed)▪K eyphasor (speed)▪P roximity probe (displacement)▪V elometer (velocity)▪T emperature (resistance temperature detector or thermocouple)▪V oltage (±30 V)▪C urrent (4–20 mA)▪D igital input▪R ead from Modbus slave devices via TCP/remote terminal unit▪I nfrared camera (thermography)▪H igh-voltage potential transformers for MCSA—120/240 V AC secondary▪H igh-current current transformers for MCSA—low-voltage secondary▪P ower (calculated from voltage x current)▪R F/radio antenna for EMSA▪D ata points from OPC UA tags▪D ata points from the OSIsoft PI System▪D ata points from AVEVA eDNA Enterprise Data ManagementVibration AnalysisMany vibration sensors, such as accelerometers, velocity sensors, and proximity probes, can ultimately provide the same type of information. Vibration signals consist of multifrequency components, and each component represents part of the vibration. These individual vibration components add up to create the overall vibration signal. You can perform two types of vibration analysis using InsightCM: Observing vibration levels to describe the waveform and analyzing spectral bands to describe the spectrum (essentially, a fast Fourier transform of the waveform).Vibration analysis focuses on either levels that describe the waveform or spectral calculations that describe specific frequency content. InsightCM includes several default level and band calculations, and you can create custom bands to trend bands that correlate with known faults, such as a bearing or gear mesh issues. You can calculate these features on Cutsforth monitoring devices to immediately detect fault conditions and trigger data collections based on the asset operating state.FIGURE 7.Continuous Monitoring Systems are compatible with virtually any sensor technology, including standard IEPE accelerometers seen mounted via epoxy to the motor in this image.InsightCM includes several industry-standard vibration analyses to help you identify faults. For example, you can use an orbit plot to see how a shaft is rotating in a bearing on a turbine and identify worn bearings or inadequate lubrication. Envelope (demodulation) analysis is commonly used for rolling-element bearings to better identify impacting frequencies that correlate with bearing faults.Features§1x and 2x Magnitude §1x and 2x Phase §Asynchronous§Crest Factor§Derived Peak§High Frequency §Peak-Peak§RMS§Synchronous§True Peak§Subsynchronous§Kurtosis§Custom Spectral Bands§Gap§Smax§ResidualAnalysis Viewers§Trend§Waveform§Spectrum§Waterfall§Full Spectrum§Order Waveform §Order Spectrum §Envelope Waveform §Envelope Spectrum§Orbit§Bode§Polar§Shaft Centerline§Table§Time Synchronous Averaging(TSA) Waveform§TSA Spectrum§AutocorrelatedSpectrum§AutocorrelatedWaveformFIGURE 8.The functions listed in the “Features” section above are available in the real-time viewer so analysts can get to a diagnosis, faster.ThermographyThe thermal Imaging Toolkit automates the process of collecting and monitoring images from infrared cameras, as seen in Figure 10. Trend data from regions of interest and alarm on transformer, motor control center, breaker box, and bus bar hot spots. Specify regions of interest (ROIs) and calculate maximum, minimum, and average temperature. With a delta feature, you can calculate the temperature difference between any number of ROIs to normalize for environmental conditions such as monitoring a transformer and looking for an outlier amongst the bushing temperatures.FIGURE 9.This InsightCM infrared thermography image shows two chilled-water pump-motor skids with a temperature differential trend line. The temperature delta between regions of interest is a common way to look for hot spots on breaker panels, bus bars, and transformers.Features▪M aximum Temperature within ROI▪M inimum Temperature within ROI▪A verage Temperature within ROI▪D elta Temperature between Two or More ROIsAnalysis Viewers▪T rend▪T hermal Image▪T ableMCSAMotor-current signature analysis (MCSA) uses voltage and current signals to identify motor faults including rotorbar damage, misalignment, eccentricity, mechanical looseness, and some bearing problems. When purchased with the MCSA toolkit for InsightCM, Continuous Monitoring Systems compute features specific to electrical data and motors in addition to the phasor and waveform analysis available.Note: InsightCM is designed for three-phase AC induction electric motors. There is not support for variablefrequency drive motors at this time.The 24x7 screening on the Continuous Monitoring System continuously samples voltage and current data at up to 10,000 samples per second looking for transients and in-rush currents. Use this toolkit to set operating states and trigger conditions for in-rush current so you never miss a startup signature.FIGURE 10.In a typical motor control cabinet install, CT signal wires run through conduit to Continuous Monitoring Systems with sensor modules for MCSA installed in an industrial cabinet.FIGURE 11.Cutsforth monitoring systems for MCSA can connect to multiple motors on a single three-phase voltage bus. One module connects to voltage/potential transformers with accompanying modules in the chassis used for current transformers.FIGURE 12.This InsightCM analysis view shows three-phase voltage and the MCSA spectrum.Features▪R MS▪L ine Frequency▪P hasor: Magnitude▪P hasor: Phase▪U nbalance▪E ffective Service Factor▪D erating Factor Analysis Viewers ▪A ctive Power▪R eactive Power▪A pparent Power▪P ower Factor▪S peed▪T orque▪T orque Ripple▪R otor Bar Sideband▪L oad▪P ercent Load▪E fficiency▪P ercent Full LoadAmps▪S tartup Peak Amps▪S tartup Time▪T rend Chart ▪W aveform ▪S pectrum ▪T able ▪W aterfall▪M CSA Spectrum▪M CSA Torque Waveform▪M CSA EnvelopeSpectrum▪P hasor DiagramFor Assets Typically on Periodic RoutesPlant maintenance teams often rely on manual, route-based data collection for less-critical plant assets. With Wireless Monitoring Devices, you can get daily machine health visibility without a trip around the plant. Wireless Monitoring Devices are designed to wirelessly transmit diagnostic (waveform) data from wired analog sensors to a Cutsforth gateway and then to the InsightCM server, connected via your enterprise IT network. Wireless Monitoring Devices, when battery powered, dramatically reduce installation cost by eliminating the need for running cable/conduit for power and Ethernet. There are currently two types of Wireless Monitoring Devices: Wireless Vibration Measurement Devices and Wireless Vibration Sensors.Wireless Vibration Measurement DevicesWireless Vibration Measurement Devices connect to standard asset-mounted analog sensors and use wireless communication to send diagnostic-quality waveform data to an InsightCM server. Install the system near the monitored asset with the built-in mounting flange. The rugged enclosure is outdoor-rated for industrial environments and can handle wide temperature ranges as well as washdowns. The wireless monitoring devices have 12 analog input channels that support accelerometers, proximity probes, tachometers, and voltage or temperature sensors. All devices ship ready to install and connect to power (either line-powered or battery-powered) and sensors. Once you have installed and commissioned its hardware, the Wireless Monitoring Device transmits data back approximately once a day (user-configurable) via a wireless gateway to the InsightCM server installed on premises or in a virtual machine in your choice of cloud provider. The device also can be manually triggered to send data back to the server.FIGURE 16.Wireless Vibration Measurement Devices acquire full waveforms and transmit the data to InsightCM via a wireless gateway.Sensor SupportThe Wireless Vibration Measurement Device supports the following sensor types out of the box: ▪A ccelerometers (IEPE)▪P roximity probes (user-provided)▪T achometers▪V oltage (±30 V)▪T emperatureWireless Vibration SensorsWireless Vibration Sensors contain an integrated triaxial accelerometer and use wireless communication to send diagnostic-quality waveform data at up to 2 kHz fmax to an InsightCM server. They also include an integrated temperature sensor that can trend temperature data. Install the sensor on the monitored asset with the built-in1/4-28 stud mount. The rugged exterior is IP66/IP67-rated for industrial environments and can handle wide temperature ranges as well as washdowns. All devices are battery-powered and ship ready to install. Once you have installed and commissioned its hardware, the Wireless Monitoring Device transmits data back approximately once a day (user-configurable) via a wireless gateway to the InsightCM server installed on premises or in a virtual machine in your choice of cloud provider. The device also can be manually triggered to send data back to the server.FIGURE 17.Wireless Vibration Sensors contain an integrated triaxial accelerometer and temperature sensor and transmit the data to InsightCM via a wireless gateway.GatingBoth Wireless Monitoring Devices are mounted near the asset and transmit data back to the InsightCM server via a wireless gateway approximately once a day (user-configurable). Because most of the wireless device’s battery consumption occurs during wireless communication with the gateway, sending data only when the monitored asset is running helps prolong battery life. Wireless Monitoring Devices have a gating feature that checks whether the asset is on before acquiring and sending asset health data. Gating can be based on acquired sensor values or external systems via Modbus, OPC UA or the OSIsoft PI System.Outdoor-Rated EnclosuresWireless Monitoring Devices are designed to either IP54 or IP66/IP67 specifications for protection from liquid, dust, and particulates. Installers can mount the systems directly outside in any climate without an additional industrial enclosure.Monitoring Device Feature Comparison。

航空电子产品振动试验夹具设计

航空电子产品振动试验夹具设计

航空电子产品振动试验夹具设计振动试验夹具用于连接振动台和试验产品,并能尽可能不失真的将振动台输出的能量传递给试验产品,在振动试验中发挥着非常重要的作用,试验的成功与否,试验结果的可信程度,与试验夹具的设计、制作及安装使用水平息息相关。

不合理的夹具将导致“过振动”或“欠振动”,使振动条件失真,无法达到预期效果,严重的会对试验样件造成破坏。

本文首先阐述了振动夹具的设计要点,然后以LRM模块为例设计其振动夹具,并使用ANSYS有限元仿真分析软件进行模态仿真,根据仿真结果对夹具进行优化处理,最后设计出优质的振动夹具。

标签:振动;夹具;ANSYS1 振动夹具的设计要点1.1 振动夹具的基本设计要求根据多年的工作实践经验,同时翻阅了的大量的文献资料,我们认为合理可靠的振动夹具首先要保证在试验频率范围内不会与受试产品发生共振耦合,导致振动失真,其次应尽可能地减少夹具的重量,增大其刚度和阻尼。

一个优质的振动夹具主要应满足以下几项要求:①最佳的夹具应使其最低的固有频率比所需的最高施振频率高50%左右,以免试验时产生谐振,大多数航空电子产品的随即振动试验频率范围为10~2000Hz,因此夹具的理想一阶固有频率应在3000Hz左右;②夹具的第一阶固有频率应高于受试产品第一阶固有频率的3~5倍,以避免发生夹具与受试产品的共振耦合,导致过振动;③夹具应做得尽可能的小而简单,由于振动台的推力有限,为保证有足够的推力富余量,在不降低刚度的情况下,夹具重量要尽量的轻;④夹具应采用对称设计,重心位置应当靠近振动台的几何中心,以减小振动偏载力矩,高度方向上重心要低,以减小横振力矩。

1.2 振动夹具材料的选择制作夹具首先要选择材料,材料性能方面应具有较小的密度、较大的刚度和较高的阻尼,且应当易于加工,同时要兼顾加工成本。

直接影响夹具固有频率与性能的因素是材料的弹性模量E与材料密度ρ之比,比值E/ρ非常重要,E决定材料的刚度,ρ决定材料的重量,其值越大越好。

设备故障的案例以及故障诊断的方法。

Equipment failure is a common occurrence in various industries, and it can lead to significant downtime, loss of productivity, and increased maintenance costs. Therefore, it is crucial to have effective methods for diagnosing equipment failures in order to minimize their impact on operations.设备故障在各行各业都是常见的现象,它会导致显著的停机时间、生产力损失和维护成本增加。

因此,必须有有效的方法来诊断设备故障,以最大程度地减少其对运营的影响。

One common method for diagnosing equipment failures is to conduct a thorough inspection of the equipment to identify any visible signs of damage or malfunction. This can involve examining the physical components of the equipment, such as belts, gears, and electrical connections, as well as reviewing any error codes or alerts that may be present.诊断设备故障的一种常见方法是对设备进行彻底检查,以识别任何可见的损坏或故障迹象。

这可能涉及检查设备的物理组件,如皮带、齿轮和电气连接,以及审查可能存在的任何错误代码或警报。

机械破损检测方法

机械破损检测方法

机械破损检测方法Detecting mechanical damage is a critical aspect in ensuring equipment and machinery operate efficiently and safely. 机械损坏的检测方法对于设备和机械的高效安全运行至关重要。

One of the commonly used methods to detect mechanical damage is visual inspection. Visual inspection involves examining the equipment with the naked eye to identify any visible signs of wear, tear, or other forms of damage. While this method is cost-effective and straightforward, it may not always be accurate in detecting internal damage that is not visible on the surface. 视觉检测是一种常用的检测机械破损的方法。

它涉及用肉眼检查设备,以识别任何可见的磨损、撕裂或其他形式的损害。

虽然这种方法成本低且简单明了,但它并不总是准确的,因为它可能无法检测到表面不可见的内部损害。

Another method for detecting mechanical damage is ultrasonic testing. Ultrasonic testing involves the use of high-frequency sound waves to detect defects and measure the thickness of materials. This method is highly sensitive and can detect even small cracks or defects that are not visible to the naked eye. Ultrasonic testing isparticularly useful in assessing the integrity of critical components such as pipelines, pressure vessels, and structural steel. 另一种检测机械破损的方法是超声波检测。

Trane Building AdvantageVibration AnalysisPredictive service for increased ReliabilityOur competitive environment calls for greater equipment reliability at lower operating costs. These needs require innovative, proven and practical solutions that can be quickly implemented to produce fast cost savings.Vibration analysis has become the preferred choice among all non-destructive methods. And it has been established that a vibration signature of a running equipment provides more detailed information on internal components condition than infrared or electrical non-destructive methods.Benefits of Trane vibration analysisEvery piece of HVAC equipment with rotating components has its own vibration signature. Any change in this signature can be used as an accurate means of identifying developing problems such as bearing wear, shaft imbalacing, and degrading screw compressor rotor tolerance. The monitoring and diagnostics system reliably detects potential defects atthe initial stage of their development and identifies the exact defect type and its severity. Vibration analysis can identify problems long before they become noticeable on the environment.Risk removalThe Trane vibration analysis allows you to switch from ‘run to failure’ mode to a more predictive maintenance mode avoiding the high costs involved with emergency repairs and minimizing expenses associated with equipment downtime.Increasing the operating reliability by improving the Mean Time Between Failure (MTBF) lowers your repair bills.A complete offerThe Trane vibration analysis is part of Trane Building Advantage program.
