| Abstract: | The significance of the research related to the wide band random vibration analysis on spacecraft and the developing history and recent status home and abroad are summarized briefly.Then,the hybrid application of Finite Element Method and Statistical Energy Analysis is used to predict the response of the whole satellite under wide band random vibration excitation,the prediction result accords with that of experiment well. |
