Do You Know that Your Accelerated Vibration Test Requirement Is Correct?

Vibration test time-compression methods have existed for decades and are well-documented. However, not all practitioners are aware of how these methods were developed and the proper utilization of the developed theory. While many sources have attempted to clarify the methodology, there is confusion on many points. The objective of this paper is to help new vibration test engineers understand accelerated testing theory and practice. The lab is a valuable training ground, but sometimes the subtleties are not communicated. A more complete understanding of the theory and practice of vibration test time-compression methods is needed when translating contract requirements into test procedures used in product development and validation.
