摘要
为保证卫星有效载荷仿真计算的可行性和精度、提高仿真效率,预测有效载荷在相应力学环境下的响应,用HyperMesh 8.0划分整机的有限元模型网格,用MSC Nastran 2005计算和分析有效载荷的过载特性、频率响应特性、冲击和随机振动.该方法对保证卫星有效载荷仿真计算的可行性和精度、提高仿真效率有重要作用;可以有效预测卫星有效载荷对力学环境的响应,较全面评估设计,进而指导改进设计.
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 simulation efficiency. It can effectively predict the mechanics environment response of satellite payload, evaluate design completely, and improve the design.
