LMS TecWare and LMS TWR, accelerating Test-based Durability Engineering 

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 fi les 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.

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.

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.
