Working with Physical Measurements from Severe Mechanical Shock & More

This training module focuses on the acquisition of transient physical measurements using accelerometers, strain gauges, and other commonly used sensors as well as working with the typically noisy data generated from these measurements. The training also covers the validation and comparison of physical test data with transient numerical simulation results. This training is recommended for those taking physical measurement data as well as those who receive or work with physical measurement/test data (that means FEA users too!).

Please note, the training concentrates on many aspects related to making good and accurate transient measurements, and then how the proper use of DSP techniques is often required to obtain improved results and correlation between physical tests and numerical simulations. The training does not discuss how to tune simulations to obtain improved correlations.

Course Objectives & Benefits

• Get BOTH the measurement/test engineer and simulation user on the same page!
• Learn about the key aspects of making a good transient measurement.
• Explore sources that cause distortions in physical tests, and then how to potentially remove them.
• Learn about the challenges of taking accurate transient accelerometer and strain gage measurements, and techniques to improve both the raw data as well as its down-stream post-processing.
• Experience how to use DFS to identify the bandwidth of the noise-floor in measurements and then apply appropriate filtering to significantly improve the noise-floor.
• Learn how to obtain better correlations between physical tests and FEA simulations.
