摘　　要：使用MSCNastran软件对空间相机部件进行频响分析仿真,对振动试验的进行起一定的指导作用,同时利用试验结果数据对仿真条件进行修正,使修正后的仿真结果和试验结果误差较小,为以后的相关分析提供方法和依据.A Frequency response analysis of a space telescope component was made using MSC Nastran on computer. It provided some useful instructions for a following vibration experiment. After the experiment, the result data was utilized to modify the simulation conditions. Therefore, the difference between the calculations and the experimental data was reduced. The method and foundation was prepared for future relative researches.
