Abstract

This study proposes a method for obtaining the enveloped energy spectrum using measured transient vibration time-history data. By combining the principles of random signal generation in control theory of vibration controller, we successfully constructed a time-domain waveform that possesses both the amplitude characteristics of the envelope energy spectrum and typical phase information from acquisited test data. using vibration table waveform reproduction technology, we conducted transient vibration environment testing on products. This method provides important technical support for future transient vibration vibration table test methods that directly utilize energy spectrum control.
