Developing Random Vibration Tests from Field Data
(course 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
• Data Grouping
• Acceleration Factors
• Final Environments

Intended Students
This class is directed towards engineers who engaged in vibration testing. It requires a familiarity with data acquisition and reduction.

This is an intensive one-day course
