New Method for Producing 6-Degree-of-Freedom Random Vibration

This paper describes one method for producing random 6-axis vibration within an accelerated test process to expedite design verification. The concept behind accelerated testing to identify failure modes and achieve product improvement is reviewed. The machine is presented as an alternative to existing technologies within the accelerated testing process. Together, the concept and machine are presented to engineers as a possible tool to verify new designs and discover non-intuitive failure modes prior to releasing a design for production. The theory of operation and the performance parameters of the machine are also discussed.
