Time domain response envelope for structural dynamic systems
A transient envelope solution method is developed for payload structural systems. This method requires that the external forcing functions are decomposed into a quasi-static part and a dynamic part. The amplitude of the peak envelope and the corresponding varying frequencies for the generalized forcing functions are required for obtaining the response envelopes. The proposed method is applied to a sample problem as well as a spacecraft structural system and the results are in good agreement with the exact solution.
