Abstract: To ensure the feasibility and precision of satellite payload simulation and improve the simulation efficiency, the response of the payload under the related mechanics environment is predicted, the finite element model of the whole machine is meshed by HyperMesh 8.0, and the overload, frequency response, impact and random vibration are calculated and analyzed by MSC Nastran 2005. The method is important to ensure the feasibility and precision of satellite payload simulation and improve the simulat
