疲劳耐久测试与分析系统

Everything you need for durability load data analysis After spending a day in the field collecting test data, the last thing durability engineers want to do is spend the next months interpreting them. Converting back and forth between different data formats, trying not to lose track of file and channel names, attempting to make sense of what was so obvious in the field. LMS TecWare is a modular suite of solutions for durability load data analysis and synthesis. It efficiently supports the processing of raw data into loading histories for virtual and physical tests. It provides all the required tools and streamlines the process from data import through reporting to delivering the loads for testing – without requiring any cryptic commands or writing complex programs. LMS TecWare can automate existing procedures and keep track of the large amounts of files that are being handled. TecWare also provides the traditional analyses such as interactive editing, rainflow analysis, fatigue-sensitive time history reduction and experimental fatigue life prediction.
Besides effective load data cleaning and validation, LMS TecWare Load Data Processing focuses on monitoring and comparison of essential loading portions from a durability perspective. With the built-in reduction methods (rainflow counting, range pair, time-at-level, spectral analysis, statistical methods….) and dedicated visualization tools, users can quickly overlay and correlate the durability impact of different road surfaces or different design variants. This helps users in selecting representative loading scenarios for further Test or CAE based Durability engineering.

Faster, easier, better multi-axial control...
Reproducing time histories on multi-axial test rigs remains a special art in many organizations. Very often, the drive file generation process takes too long. All too often, engineering intuition and years of experience are required to gain control of the rig. Invariably, little use is made of the valuable data that are generated... LMS/IST RS Time Waveform Replication provides the most advanced and flexible control features on the market today. Some modules incorporate new technologies that help slash the time required to reproduce measured or synthesized drive signals. Work that previously took a week is now often finished in a day. Others show what is happening during the process - the quality of the system model, rainflow counting and range pair diagrams, structural FRFs, time histories and error displays... All will turn an intuitive art into a faster, safer and more effective simulation process.

LMS TecWare Load Data Processing
A critical factor in successful durability engineering is gaining a precise understanding of the loads that your product will undergo during its lifetime. The use of unreliable load scenarios for Test or CAE based durability engineering inherently implies invalid fatigue performance prediction.
LMS/IST RS TWR allows the comparison of target and measured road profiles and the updating of rig control signals to be executed fully automatically.

LMS TecWare Load Data Processing has all the standards, hooks and connections to import data from any source: vast amounts of field load data collected after a day out on the proving ground; or predicted load data synthesized using multi-body simulations. If you are processing field load data, it is more than likely that your data will need to be cleaned and validated. LMS TecWare contains a set of tools which help you edit, manipulate and validate your data in every way.

Accelerating Test-based Durability Engineering
Executing extensive field tests to validate the durability performance of mechanical designs is very expensive and time-consuming. This pressures automotive OEMs and suppliers to efficiently reproduce equivalent laboratory tests. LMS TecWare and LMS TWR offer a robust solution that integrates and automates the physical durability testing workflow, from load data processing over test schedule optimization up to drive file generation for test rig campaigns. This complements the IST solution for test rig setup, control and data management, and durability test execution, to result in the complete and integrated Durability Alliance software suite for environmental durability simulation.
The Durability Alliance
The Durability Alliance formed between Instron Structural Testing Systems, LMS International, Kistler Instrumente AG and Team Corporation is working together to provide world-class hardware and software solutions for physical testing, virtual prototype simulation and engineering analysis software. The added value delivered through seamless integration and support enables customers to reduce time to market and improve product quality and performance.
The Alliance has been driven by close association with its customers to ensure a tight integration of testing and simulation software with damage monitoring and analysis. LMS and IST formed joint development teams and RSTWR (Time Waveform Replication Software) is the prime example of this joint effort.
LMS TecWare’s rainflow counting technology is applied to monitor and compare the durability-relevant aspects of road load data.
LMS TecWare efficiently determines sets of compressed load data histories that preserve the same damage potential as originally present.
