Abstract

In order to improve the fatigue evaluation system of the satellite in the transportation environment, a fatigue analysis method of satellite transportation environment based on the digital twin was explored in this paper. At first, the basic theories and method of fatigue analysis are introduced in detail. The fatigue damages of the satellite in the transportation environment are evaluated by using the random vibration and sinusoidal vibration stress fatigue analysis separately. And then, digital twin fatigue models based on the acceleration response of random vibration and sinusoidal vibration are established. Finally, fatigue models are utilized to analyze the fatigue damage to the satellite in the transportation environment and are compared with the stress fatigue models before. The results show that all the fatigue damage keeps in accordance with each other verifying the accuracy of the fatigue model based on the digital twin presented in this paper.
