Abstract

Abstract: In order to ensure reliable connection and separation between satellites and the launch vehicles, a dynamic modeling method of a certain type of non-explosive separation device based on contact theory is proposed to carry out more accurate results in this paper. After analysis on the actuation principle of the non-explosive separation device, the source of impact response is clarified. Then the contact model is established based on the contact theory and the dynamic simulation model is established. The dynamic simulation results show that the shock acceleration of housing is no more than 300g, it is consistent with the experimental results performed by other workers. The simulation model can be utilized for the design and validation of the non-explosive separation device to provide a reliable basis for subsequent optimization.
