Abstract
In the working process of the non-pyrotechnic and lower point-to-point impact satellite-rocket unlocking and separation device, the swing arm rotation time and the impact force generated by the collision cannot be ignored for the whole separation process. In this paper, the dynamics and Herz contact theory are used to the dynamic modeling and simulation of the first and second stage swing arms in the separation device by means of the numerical analysis software. The simulation curves of the swing arm rotation time vs. impact force are obtained, and the correctness of the theoretical model is verified by experiments. The mutual comparison between the simulation results and the experimental results shows that the data consistency is good. The calculation results have a high reliability.关键词
