Design and Verification of Satellite Docking Ring Damping Device

Aiming at the problem that the satellite with the same platform cannot meet the requirements of various vehicle mechanical environments, a docking ring vibration reduction device is designed and tested. Firstly, by analyzing the functional characteristics of the satellite docking ring, combined with the vibration reduction method of metal rubber materials, the vibration reduction device of the docking ring is designed, and the dynamic model of the system composed of satellite and docking ring damping device. Then, the effectiveness of the butt ring damping device designed in this paper is verified by sinusoidal vibration test and random vibration test. Secondly, the finite element analysis of the butt ring damping device is carried out, and the finite element analysis results are compared with the test results to verify the correctness of the analysis model. Finally, the docking ring vibration isolation device is applied to HJ 2 satellite, and the application effect of the device is verified by dynamics analysis.
