Abstract: The vibration data of the solar array of satellites in transportation are analyzed. It is shown that the environment of the airplane transportation and the rail transportation are better than that of the road transportation. The vibration responses in transportation are primarily of low-frequency and small magnitude, and the lateral vibration responses are significantly smaller in magnitude than the longitudinal responses. The transportation vibration responses are influenced by the road conditions and the speed of the vehicle. The damping performance of the shock absorber varies in different cases, and the vibration response of the solar array transported alone is basically the same as when it is transported with the satellite. Reliability analysis results indicate that transportation will not lead to fatigue damages of the solar array.
