Developing Random Vibration Tests from Field Data
(SPEC 501)
Course Description
Random vibration testing is primarily used to simulate real-world steady-state -- or stationary -- environments. However a technique exists for developing lab-test environments from non-stationary data. The resulting tests can compress thousands of hours of real-world environments into a test lasting a few hours -- without exceeding the real-world levels.
Syllabus
- Vibration Environments
- Stationary and Non-Stationary vibration
- Power Spectral Density Plots
- Review of Time Histories
- Data reduction procedure
- Enveloping of PSDs
