| Abstract: | Based on the method of micro-vibration modeling of IME, a multi-flexible coupling dynamics model is developed to analyze the micro-vibration of a satellite. The results agree well with the ground micro-vibration test, which shows that the model could be used to test the micro-vibration behavior of the satellite in orbit and the transfer characteristics of micro-vibration signals in the satellite structure. |
