某星载设备环境综合仿真

摘要

In this paper,the dynamics and thermal characteristics of a satellite-borne equipment′s are analysed and calculated with Ansys and Flotherm FEM software.Three types of dynamics simulation are performed which including modal analysis, harmonic analysis and random vibration analysis.The method of model simplification and assembly is also discussed in detail as well as the determination of the boundary conditions .%采用有限元分析软件ANSYS和Flotherm，对某星载电子设备进行了模态、谐响应和随机响应的动力学仿真分析和热仿真分析。介绍了在有限元分析中模型简化，模型装配、边界条件设置等方面的方法和经验。
