DVM-1000 数字振动测试仪操作手册说明书

Operation ManualDigital Vibration TesterModel No. DVM-1000Phase II Machine & Tool, Inc.283 Veterans Blvd Carlstadt, NJ. 07072 (201) 933-6300 Features:The DVM-1000 is a compact and simple to operate vibration tester. It’s an ideal tool for obtaining balance and alignment data for all types of rotating objects such as heavy-duty machinery or any fixture that uses a motor as a source of power.The high temperature piezoelectric sensor has a removable mounting base for attachment of a supplied stinger probe. It also is equipped with AC output socket for easy headphone hook up. The DVM-1000 has a large 18mm LCD that will display the data in four (4) measurement modes; Acceleration, Velocity(RMS), Displacement and RPM. Auto shut-off will conserve batteries and will still save all previous stored data.Specifications:Acceleration Peak Value: 0.1 – 200 m/sor 0.3-656 ft/m/s Frequency Range: 10Hz-1KHz Frequency Range: 10Hz-10KHzVelocity(RMS) RMS: 0.01-400 (mm/s)or 0.004 -16.0 inch/sFrequency Range: 10Hz-1KHzDisplacement Peak to Peak 0.001 – 4.00(mm)or 0.04-160milFrequency Range: 10Hz-500HzRPM (revolution)60-999,990 r/min(readings should be multiplied by 10 if the displayis set for “10”Frequency 1 – 20KHzAccuracy +/-5% +2 digitsOperatingTemperature/Humidity0-50°C / below 90%RHOperating Output AC output 2.0V peak full scale Load resistance: above 10k Power Supply 4-AAA BatteriesDimensions 124 x 62 x 30mm (4.9 x 2.4 x 1.2:)Weight 120g (not including batteries)The DVM-1000 Kit includes:1pc Powerful Earth Magnet1pc Accelerometer1pc Stinger Probe (Cone)1pc Stinger Probe (Ball)Operation Manual & Carry CaseFront Panel Descriptions:3-13-2 3-63-83-7 3-53-4 3-33-113-103-93-12Set Up Procedure:1.Connect the accelerometer to the input connector on the right side of the unit bythreading the socket gently until it locks in place.2.Press the Power Button to turn unit on.3.Place the accelerometer, with the magnetic base firmly attached to the machine. Youshould allow a few seconds for the readings to stabilize before taking a reading. Machine vibration may vary with time, in which case the maximum and minimum readings may be recorded. The machine surface must be sufficiently flat to permit the magnetic base to solidly attach to it. If the magnetic base is not attached properly, you will not be able to obtain accurate readings at higher frequencies. If the measurement surface is not magnetic or if the space is limited, the “Stinger” probes can be used in place of the magnetic base. When using the Stinger probe hold the tip against the machine with just enough force to prevent chattering. The stinger must be positioned perpendicular to the desired measurement surface.A steel disc or washer may be cemented to a non-magnetic surface to permit usage of themagnetic base. For Maximum accuracy of Acceleration (g) measurements, the accelerometer should be temporarily mounted on the machine surface with the supplied (M5) threaded mounting stud.Measurements made in more than one vibration mode can reveal something of the nature of the vibration signal. A high acceleration reading combined with a low displacement reading is indicative of a high frequency vibration. Conversely, a low acceleration reading combined with a high displacement reading is indicative of a low frequency vibration. Velocity is usually the preferred measurement when a single reading is to be recorded. Consult the machines operation manual or the manufacturer if you are in doubt of the measurements to be made.The supplied vibration chart should be used as a guideline for determining machine condition. The best indicator of machine condition is a carefully collected and recorded history database. Changes in machine condition over time become readily apparent and permit repairs to be made prior to machine failure.4.Press the Function button to toggle through the 3 main measurement parameters; as wellas RPM and Frequency readings. The three main measurement scales are typically used for vibration testing.a)Acceleration: Normally measured in m/s2 has excellent high frequency capabilitiesand is therefore very effective in determining faults in bearings or gear drives.b)Velocity: The most commonly used vibration parameter. It’s used for vibrationseverity measurements in accordance with ISO 2372 which contains guidelines foracceptable vibration levels of machinery under different power categories. Theseguidelines are presented in a table in the back of this manual. Velocity is typicallymeasured in cm/s or Inch/s RMS (centimeters or millimeters per second). Note: thisinstrument measures in cm/s. If you are more familiar with measurements in mm/sor need to compare your measured values directly with the vibration severity chart inthis manual, you must multiply the value by 10.c)Displacement: This parameter is typically used on low speed machines because ofit’s good low frequency response. This is NOT recommended for monitoring bearings.Units are measured in Mil or mm equivalent peak-peak.Calibration:The DVM does not need a scheduled (daily, weekly, monthly) calibration performed however, the calibration should be verified yearly by Phase II or a qualified calibration facility.Battery Replacement:When the battery symbol appears on the display, its time to replace the batteries.Slide the back cover off and remove and properly dispose of the old batteries. Replace with fresh set of batteries paying careful attention to the polarity.Maintenance:Be sure to keep this unit free of dirt, dust, liquids or viscous fluids. Its also best to store this unit in a temperature controlled environment when not in use for a long period of time.If the DVM-1000 malfunctions, contact Phase II tech support directly for instructions. Any attempt at internal repair will void any stated or implied warranties.Vibration Charts:ISO 10816This recommendation, release in August 2000, establishes the general conditions and procedures for the measurement and evaluation of vibrations using measurements made on the non-rotating parts of a machine. It also provides general evaluation criteria related to both operational monitoring and acceptance testing established primarily with regard to securing reliable long term operation of the machine.ISO 10816-3 separates the working conditions into four zones:•Zone A (Green): Vibration values from machines just put into operation•Zone B (Yellow): Continuous operation without any restrictions•Zone C (Orange): Condition is acceptable only for a limited period of time•Zone D (Red) Dangerous vibration values-Damage could occur at any time.It also defines four groups of machines, according to their size, base and purpose.Ranking:A=Vibration values from machines just put into operation B= Continuous operation without any restrictionsC = Condition is acceptable only for a limited period of timeD = Dangerous vibration values-Damage could occur at any timeNEMA MG1-12.05(Maximum vibration of motor that generates more than 1 horsepower)RPM (Rev) Displacement (p-p) (µm)3000-4000 25.4 1500-2999 38.1 1000-1499 50.8<999 63.6NEMA MG1-20.52(Maximum vibration of high power induction motor)RPM (Rev) Displacement (p-p) (µm)>3000 25.4 1500-2999 50.8 1000-1499 63.6<999 76.2 Example of Analysis chart:it’s highly suggested that you design your own chart based upon your testing procedure and application.Main Headquarters: U.S.APhase II Machine & Tool, Inc.Carlstadt, NJ. 07072 USATel: (201) 933-6300Fax: (201) 933-3801General E-Mail: ******************BEIJING, CHINAPhase II Measuring Instruments (Beijing) Ltd.

As a result, the diaphragm is pushed back by the spring and the valve opens, allowing more gas in from the supply until equilibrium is reached between the outlet pressure and the spring.The outlet pressure is a function of the spring force which may be modified by the adjustment knob. The outlet pressure and the inlet pressure hold the quad ring poppet assembly in the closed position against the force of the spring.Model 8310 / 8311Precision Pressure Regulator5P r e c i s i o n P r e For more information call +1 603 595 1500 or email ppfinfo @Mechanical IntegrationDimensions83108311Model 8310 / 8311Basic DimensionsUnits In (cm)Precision Pressure Regulator6For more information call +1 603 595 1500 or email ppfinfo @Model 8310 / 8311Typical Flow DiagramVOC Emissions Monitoring AnalyzerPrecision Pressure Regulator7P r e c i s i o n P r e s s u r e R e g u For more information call +1 603 595 1500 or email ppfinfo @Model 8310 / 8311Ordering InformationInstallation Guide• For NPT connections, a high quality sealant compatible with the customer’s process gas must be used.• May be installed in any orientation.• Support inlet and outlet piping to reduce strain on regulator body.Key Things to Remember:• To minimize your Helium gas costs, consider using 2.5 or 5 psig Pressure Range (0.17 or 0.34 barg) only available from Parker. • Choice of Diaphragm Materials – Stainless Steel Diaphragms provide extremely low permeability.

There are several types of movement: orbital, reciprocating, and refrained orbital, such as SKR series (orbital); MS series and vortex mixers (refrained orbital). The SKR mixers generate smooth orbital (circular) and turbulence effect on the liquid, creating good mix and aeration for the samples and suitable for mixing the samples in flask and other larger containers. The SKR is also widely used in liquid culture. However, the SKR is not suitable for small vials since more vigorous movement needed for mixing the liquid in small containers.The Micro‐plate shakers are developed for the mixing of small vials. The shakers generate agitation effect through refrained orbital movement.Figure 1: Overview of the lab scale orbital shaker (SKR‐202, Digital). 1 Electrical socket;2 Carriage platform;3 Main LED on Digital front panelFigure 2: Overview of the mini microplate shaker (SKR‐13, Analog). 1 Electrical socket;2 Slip‐proof platform;3 Main Switch on Analog front panelOperationAlways install the carrier or platform before turn on the machines. All platforms or carriers are shipped in pre‐installed status. For safety reason, please check all the locking screw and tighten again if necessary. The locking screws might be loosened during transportation!Place the machines on the flat and steady surface and keep away from other objects for safe operation.Check the electrical safety status and the power switch must be in “OFF” position before plug into the power outlet. The machines come with IEC electrical socket and double fuses for safety operation.Load the samples first before turning on the machine. Be aware of loading sample evenly and never overload the samples.Always start with low speed and gradually adjust the speed, especially for the analog model.For SKR series, use 200 rpm maximum at the high loading.There are two different types of control in the shakers: digital and analog. Both control modes can adjust the speed and timer of the shakers.1. Digital Control of Speed and TimersFigure 14: Overview of the front panel of the digital control mode. 1 Start/stopbutton; 2 Mode button; 3 Indicator beneath “rpm”; 4 Indicator beneath “time”;5 Digital Read out;6 On/Off switch and Adjustment for Time and SpeedThere are two buttons and one knob on the digital panel: The knob is the main switch for turning on the machine and adjusting the speed and timer; the mode button has the selection function to either adjust the timer or the speed; the start/stop button is used to start or stop the mixing process. The panel has LED numeric display and red indicators.6illuminate, and when pressing the mode button, the read indicators underneath the rpm and minute alternatively illuminate to show the status of display.1.1 Press the knob to turn on the unit. The LED display the number of last saved rpm and timer setting. And the indicator underneath the rpm illuminate, adjust the rpm by the knob to desired value. And move the illuminated indicator from underneath rpm to minute by pressing the mode button, the display will show the set timer and change to the desired timing value, and finally press the start/stop button to start the machine. If using the knob to turn off the machine, the set timer and speed will automatically be saved, and carry on the next time operation.1.2 Adjust the timer: press mode button until the indicator underneath of min illuminate, turn the knob to desired count‐down minute. To disable the timer, just turn the knob to ‐‐‐, the unit will continuously operate until manually stopping the unit. When the timer reaches to zero, the unit stops and sounds an alert.The default time unit is minute (displayed nn:nn), but when turning the knob over 99:99, it displays H:nn. The maximum set time is 9 hours, i.e. 540 min.1.3 The speed and timer can be adjusted during operation without stopping the machine. Suggest users to use lower speed to start the machine and adjust the speed to optimum mixing status slowly to avoid the spill or safety problems during the operation.2. Analog Control of Speed and TimersFigure 15: Overview of the front panel of the analog control mode. 1 Timer knob;2 Main switch;3 Speed knobThere are two knobs and one main switch on the front panel of the analog types of the mixers. The main switch has three stages function: ON, OFF and Timer. For continuous operation, place the switch to the “ON” position, and turn the rpm knob (on the right hand side) to desired speed. When using timer, place the switch to “Timer” position, and adjust the speed using speed knob. Before turning on the machine, please turn the speed knob all the way to the left hand side (minimum level)! And adjust the speed gradually.Maintenance and ServiceThis range of equipment only requires routine cleaning for the maintenance.

MODAL 50A 振动测试器说明书

MODAL 50AExcitation Made Easy!THE EXCITER - #1 SELLING WORLDWIDE"The MODAL 50A along with MB's MODAL APPLICATIONSEXPERTISE have revolutionized modal testing!" This Exciter wasdesigned by a team of world-respected modal testers, includingUniversity of Cincinnati professors, to eliminate problemsencountered when using traditional shakers for modal tests. TheMODAL 50A slashes setup time to a minimum! Conveniences infixturing and setup like the clearance hole through the armatureand shaker and a collet chuck for gripping a threadless stingermake easy the attachment of the MODAL 50A to a test structure.50 pounds dynamic force from an Exciter weighing little more than50 lbs makes it portable and easy to setup by one person.THE COMPANY - UNIQUELY QUALIFIEDMB's three principals (SDRC alumni) have over seven decades of combined experience performing extensive dynamic testing - both in the USA and Europe. These experienced test veterans have solved real-world test challenges, and have helped hundreds of new and experienced modal testers alike properly apply the right excitation source to achieve good modal data faster! Choosing an MB Modal Exciter gains you access to applications experience unsurpassed in the marketplace today ... whether you need custom-tailored testing solutions ... on-site consulting ... seminars on theory, applications, excitation ... practical hints for acquiring valid modal data ... you'll get it with MB Modal Exciters.APPLICATIONS EXPERTS - BEHIND EVERY EXCITERThe MODAL 50A (and multiples thereof) is ideal for excitingstructures smaller than say, a full-size automobile. Totalvehicle modal tests on anything larger (truck, jet, even aspace shuttle) requires multiple MODAL 50A's or the MODAL250A.Modal testing of structures needs an Exciter that is highlyportable and easy to setup and operate. The lightweight,compact MODAL 50A was designed with these needs inmind. A center bore extending through the armature,housing, trunnion base, and inertial masses allows a stingerto be easily positioned along its axis. It may then be placedas close to the test article as desired and the chuck tighteneddown to grip the stinger firmly. The stinger need not be cutoff, thus retaining flexibility for future use in differentorientations and applications.The ideal stinger would be infinitely stiff in the axial direction and have no bending stiffness. Since this is not possible, it can be approached with a pre-loaded thin wire. Replacing the 1/8" stinger with piano wire is easy by simply changing one of the collets provided in the Accessory Kit. Once installed, the wire can be pre-loaded using bungy cord and a small block pulley. An oscillatory force of 50 pounds keeps the tension in the stinger while delivering peak dynamic force. This virtually eliminates measurement errors due to bending moments and side loads that can result when using compression loading of traditional stingers.25865 Richmond Rd · Cleveland OH 44146 · 216-292-5850 · fax 216-292-5614 · email mbd@mbdynamics · 1981EASY TO FIXTURE & SETUP -- SLASHES SETUP TIME•Clearance hole through armature and shaker allows unlimitedpositioning along the axis of the stinger•Collet chuck with clearance hole through armature and shakerprovides easy attachment of "one size fits all" stinger•'Piano wire' minimizes cross-axis measurement errors; allowslarge static force to be applied without derating 50 lb dynamicforce•Quick disconnect turnbuckles for adjustable suspension andeasy, 6 dof positioning•Lightweight shaker, easy-mount inertial masses/accessoriesallows one-man setup and portability to remote locations•Trunnion base with two hand-knobs and three screw feet allowadjustment to virtually any excitation angle•Quick connect/disconnect of additional mass supplies largeinertial restraint for low frequency testsUNIVERSAL -- NO NEED FOR 2 LBS FORCE OR 6" STROKE SHAKERS•1" stroke - sufficient for flexible structures and low frequency "suspended shaker" tests•50 pounds dynamic force - enough for large test articles such as mid- to full-size automobile•Lightweight armature (<0.4 lb) enables testing small items•Broad usable frequency range (1-4000 Hz) handles almost every modal survey•Ideal for multi-shaker random, single-point random, multi-point sine dwell, and even burst randomACCURATE -- FEWER MEASUREMENT ERRORS DUE TO FIXTURING•The 'current mode' of MB's SS250VCF amplifier virtually eliminates mass loading of very small test items •Lightweight armature minimizes mass loading - dramatically reduces force drop-off at resonances of the test specimen •Low armature axial suspension stiffness (<15 lbs/in) assures shaker dynamics are decoupled from the test specimen’s •Ultra thin stinger decouples force inputs in all directions except the driven axis - avoids "cross axis" error in force measurement•Applies/Maintains pre-loaded tension to the stinger, eliminating buckling problems - results in superior forcing function!

科学实验：悬挂质量的弹簧振动说明书

For a weight of mass m suspended from the spring, the fol-lowing therefore holds:(2)22ddxm k xt⋅+⋅=.This applies as long the mass of the spring itself and any friction that might arise can be neglected.In general, solutions to this equation of motion take the follow-ing form:(3) ()sinx t A t ⎫=⋅+ϕ⎪⎪⎭.This will be verified by experiment by recording the harmonic oscillations of a coil spring pendulum as a function of time with the help of an ultrasonic motion sensor and matching the measured data to a sine function.The ultrasonic motion sensor detects the distance between itself and the weight suspended from the spring. Other than an offset for the zero point, which can be compensated for by calibration, the measurement corresponds directly to the vari-able x(t) included in equation 3.The period of oscillation T is defined as the interval between two points where a sine wave crosses the zero axis in the same direction. From equation (3) it can therefore be seen to be equal to:(4) 2T=πIn order to verify equation (4), the measurements are made for various combinations of mass m and spring constant k, whereby the period of oscillation is determined from where a curve matching the data crosses the zero axis or by matching the curve to equation (3). The spring constants are also to be established by static measurements and compared with those obtained from dynamic measurements.LIST OF EQUIPMENT1 Set of Helical Springsfor Hooke‘s Law U40816 10033761 Set of Slotted Weights, 10x 10 g U30031 10032271 Set of Slotted Weights, 5x 50 g U30033 10032291 Tripod Stand, 150 mm U13270 10028351 Stainless Steel Rod, 1000 mm U15004 10029361 Clamp with Hook U13252 10028281 Ultrasonic Motion Sensor U11361 10005591 3B NET lab™ U11310 10005441 3B NET log™ U11300 1000539/40 1 Pocket Measuring Tape,2 m U10073 1002603 EXPERIMENT SET-UP AND PROCEDURE Note:The experiment is carried out using spring pendulums involv-ing coil springs with with spring constants specified as k = 2.5, 5 and 25 N/m by way of example.Static measurement∙Set up the apparatus for the measurement as shown in Fig. 1.∙Suspend one of the Hooke’s law springs (nominal values of k = 2.5, 5, 10, 15 and 25 N/m) from the clamp with hook.∙Depending on the stiffness of the spring, add the weights from the 10 x 10 g or 5 x 50 g sets of slotted weights to the spring one after the other, then use the pocket tape measure to find the extension s and enter it into Table 1.

MécaniqueOscillationsϕ1ϕ2ϕϕϕ12 == ϕϕ- = ϕϕ12= ϕϕ-ϕOscillations coupléesENREGISTREMENT ET EVALUATION DES OSCILLATIONS DE DEUX PENDULES IDEN-TIQUES COUPLES.UE105060003/16 CWNOTIONS DES BASE GÉNÉRALESLorsque deux pendules couplés oscillent, de l'énergie est va et vient entre les deux pendules. Si les deux pendules sont identiques et que leurs os-cillations sont excitées de telle manière que l'un des pendules se trouve au départ en position de repos alors que l'autre pendule est élongé au maximum, le transfert d'énergie est même intégral. C'est-à-dire qu'un pendule est entièrement au re-pos, tandis que l'autre oscille avec une amplitude maximale. La durée entre les deux arrêts d'un pen-dule ou, d'une manière générale, entre deux mo-ments où le pendule oscille avec une amplitude minimale, est la période de battement T ∆.Les oscillations entre deux pendules mathématiques identiques couplés peuvent être décrites comme super-position de deux oscillations propres. On peut observer ces oscillations propres en excitant les deux pendules à des oscillations en phase ou en opposition de phase.Dans le premier cas, les pendules sans influence du couplage oscillent à la fréquence des pendules non couplés ; dans le second cas, sous l'influence maximale du couplage, ils oscillent à la fréquence propre maxi-male. Toutes les autres oscillations peuvent être repré-sentées comme des superpositions de ces deux oscilla-tions propres.On obtient pour le mouvement des pendules l'équation suivante (pour petits angles d'élongation ϕ1 et ϕ2) :()()0012222111=ϕ-ϕ⋅+ϕ⋅+ϕ⋅=ϕ-ϕ⋅+ϕ⋅+ϕ⋅k g L k g L(1)g : accélération de la pesanteur, L : longueur de pen-dule, k : constante de couplageFig. 1: A gauche : oscillation couplée générale.

Fig. 6) et lire l'intervalle de temps des curseurs sous le dia-gramme.Le quotient obtenu à partir de l'intervalle de temps du curseur et du nombre de période incluses donne la période d'oscillations ,T 6851=4. Comparaison de la période de battement et de la période d'oscillation avec les valeurs calculées à partir des périodes d'oscillation proprePour la période d'oscillation T de l'oscillation couplée avec battement maximum, on obtient à partir de l'équa-tion (8) :s ,T T T T T ––68112=+⋅⋅=++(9)Cette valeur peut être comparée avec la valeur de me-sure T = 1,685 s.Le calcul de la période de battement T ∆ s'effectue de la même manière. Il faut toutefois tenir compte du fait que celle-ci est généralement définie comme le temps s'écoulant entre deux immobilisations d'un pendule en position de repos. Cela correspond à la moitié de la durée de période du terme cosinus de modulation ou du terme sinus de l'équation (7).s T T TT T ––26=-⋅=++∆ (10)Cette valeur peut être comparée avec la valeur de me-sure s T 25=∆.L'écart d'environ une seconde par rapport à la valeur de mesure peut paraître de prime abord important. Il est cependant dû à la différence entre les périodes d'oscil-lation propre dont il dépend sensiblement. Une variation de quatre millisecondes qui se situe à peu près dans la plage de précision de mesure maximum atteignable dans le cadre de cette expérience pour les périodes d'oscillation propre, suffit déjà à provoquer une modifi-cation de la période de battement d'une seconde.5.

Pour calculer la constante de rappel, il est donc recommandé d'établir une relation avec la période de battement, relation que l'on obtient en intégrant l'équation (4) dans l'équation (8) pour obtenir l’inconnue k dans l’équation ci-dessous.()+∆∆ω⋅ω-ω⋅⋅=22L k(12)On exprime à présent les pulsations par les périodes d'oscillation et on les intègre dans l'équation (11).m N 5322222,T T T T g m dL D =⎪⎪⎭⎫⎝⎛+⋅⋅⋅⋅=∆+∆+ (13)。

monitor the data and present customers with easy-to-read reports. Also, technicians have the ability to remotely run their pressure tests from the laboratory, their desks, or anywhere outside the containment enclosure.Building theAcquisition SystemAn incident during a typical high-pressure test prompted Perkin Elmer Fluid Sciences to build a containment enclosure around the test stations. Although an enclosure increases safety, it also makes the technician’s job of continuously monitoring and adjusting the mechanical components within the station (mechanical relays,pressure, temperature, and more)increasingly difﬁcult. In addition to safety concerns, Perkin Elmer Fluid Sciences wanted to improve the accuracy of the tests and provide clients with reliable, easy-to-read reports. We tightened tolerances usingautomatic data collection instead of manually reading from gauges. Also, handwritten reports were no longer acceptable to many of Perkin Elmer Fluid Sciences’customers.by Ellen Byington, Senior Manager,Acquired Data Solutions, Inc. (ADS)The Challenge: Automating safe and reliable high-pressure,high-temperature,and high-load motion test procedures for aircraft components.The Solution: Developing a rugged,safe,and automated LabVIEW-based data acquisition system that incorporates National Instruments FlexMotion ™hardware and aprogrammable logic controller (PLC).IntroductionPerkin Elmer Fluid Sciences (formerly EG&G Pressure Sciences, Inc.) buildscomponents for aircraft manufacturers such as McDonnell Douglas, Boeing, andGeneral Electric. In the past, Perkin Elmer Fluid Sciences performed threshold tests on the components using manual test stations.These tests took a long time to run andrequired constant supervision. Safety,accuracy, repeatability, and customersatisfaction motivated the company to seek an automated approach to performing the tests. Using LabVIEW , FlexMotion, and the SQL T oolkit, ADS designed an unmanned test station for data acquisition that centered on a PLC.

T o meet the need for an unmanned test station, we designed a system that centered on a PLC. A PLC has a low failure rate in industrial applications and can control several critical functionssuch as collecting sensor data andcontrolling relays to open and close pressure valves.

The application also permits technicians to enter manual inputs that are not gathered by the PLC. In case of a system failure, the application shuts down the test and puts the system into a safe mode.

Amber软件中动力学模拟的步骤

Molecular Dynamics simulation——从能量最小化到实际模拟 1 基本流程图1）概述前面我们已经得到了Amber 用来动力学模拟的prmtop 和inpcrd 文件，它们分别是参数文件和坐标文件。

我们先从一条命令说起来解释Amber 是如何做动力学模拟的： sander –O –i mdin –o mdout –p prmtop –c inpcrd –r rst –x mdcrd 动力学过程是一个连续地解牛顿运动方程的过程：上一个牛顿方程结束时，蛋白质中各原子的位置和速度保留给下一个牛顿方程，惟一改变的是原子的加速度，它会根据各种势能函数重新计算（势能随原子坐标改变：E=f （r,…））。

只不过每个牛顿方程的时间很短，短到fs （10-15s ）级，Amber 软件提供的sander 主程序可以用来自动地做这样的数值计算。

它需要参数文件（prmtop ）、坐标文件（inpcrd ）、sander 程序配置文件（mdin ）来启动运行，我们已经有了前两种文件，本节内容最主要的就是讲解如何配置我们需要的动力学模拟。

sander 程序运行过程中会输出临时文件（rst ）保存坐标和速度，还有轨迹文件（mdcrd ）。

2）动力学过程从基本流程图可以知道，一般的动力学过程也就可以分为三步：能量最小化（minimization）、体系平衡（equilibrium）、实际动力学模拟。

由于我们进行的初始结构来自晶体结构或同源建模，所以在分子内部存在着一定的结构张力，能量最小化就是真正的动力学之前释放这些张力，如果没有这个步骤，在动力学模拟开始之后，整个体系可能会因此变形、散架。

另外，由于动力学模拟的是真实的生物体环境，因此必须使研究对象升温升压到临界值，体系达到平衡，才能做实际的动力学模拟。

2 各流程输入文件要通过Amber软件做动力学模拟，需要明白如何去配置上述过程中的每一步。

一般来说就是指定一些键/值对。

振动控制阀性能试验台的设计王文娟【期刊名称】《《流体传动与控制》》【年(卷),期】2012(000)004【总页数】5页(P37-41)【关键词】振动控制阀; 性能试验; 数据采集; 数据处理【作者】王文娟【作者单位】泊姆克(天津)液压有限公司天津 300461【正文语种】中文【中图分类】TH137引言随着我国“十二五”规划对交通、水利、能源等基础设施建设项目投资力度的加大，对振动压路机的市场需求量也日益增长，用户对压路机性能的要求也越来越高，除了能满足作业质量要求外，还对操作者的舒适性、设备节能、可靠性等方面提出了更高要求，为了满足客户需求，本公司设计开发了一种新型压路机振动控制阀。

振动控制阀是自行式振动压路机液压振动系统的关键控制部件，其性能直接影响压路机的作业质量、经济性和耐久性。

为了测试振动控制阀的性能，模拟振动压路机的现场使用工况，通过试验及时发现问题并加以改进，从而有效保证产品的出厂质量，提高产品的市场信誉，因此开发研制振动控制阀的性能试验台是很有必要的。

1 试验台的设计方案1.1 主要参数振动控制阀是以国内的机重为20 t级振动压路机开式液压振动系统为基础，并考虑机重向上、下延伸配套的需要，为了消除现有配套产品的某些缺点而设计开发的，其主要技术参数为：通径Dg25；流量220 L/min；安全阀全开压力18 MPa（可调）；息振压力13.5 MPa（可调）；最大节流流量60 L/min。

振动压路机开式液压振动系统中，齿轮泵为系统提供液压能，其排量为100 mL/r；齿轮马达将液压能转换成机械能，驱动压路机振动轴旋转，其排量为100 mL/r；振动控制阀对齿轮马达的旋向和速度进行控制；发动机标准转速为2200 r/min。

因此，为测试振动控制阀的性能，模拟振动压路机的使用工况，拟开发此振动控制阀性能试验台。

试验台的主要技术参数见表1。

表1 试验台的主要技术参数1.2 设计标准根据国家标准GB/T 7935《液压元件通用技术条件》的要求，测量准确度等级分为A、B、C三级，型式试验不应低于B级，出厂试验不应低于C级。

满足GB/T 10071-1988 《环境振动测量方法》标准对振动测量仪器的要求，也符合ISO 8041：1990《人体对振动的响应——测量仪器》。

环境振动对人体的影响与振动的加速度有效值、振动的频率特性、振动的作用时间、振动的方向和部位等等因素有关。

评价振动对人体的影响的基本量是频率计权加速度a W或频率计权加速度级VL W（简称计权振级）：频率计权加速度(指数平均) a W：按公式4-1进行均方根计算( 1)计权振级：均方根计权加速度a w与基准加速度a0的比值取以10为底的对数再乘以20，即VL W=20l g(a w/a0) (dB)(2)式中：a W为频率计权加速度有效值（m/s2）a0为参考加速度(10-6 m/s2)。
