摘　　要：主镜组件作为空间相机的关键部件,对其进行充分的随机振动试验是必不可少的,而试验环境仿真预示可以为试验条件的合理制定提供参考依据。本文对空间相机主镜组件结构建立仿真模型,通过随机振动试验仿真计算,预示了主镜组件在随机振动环境下的加速度及应力响应,验证了结构设计方案的可靠性,为相机结构设计初始阶段的力学环境条件提供合理的参考依据。As an important component of space camera,the primary mirror component must be tested sufficiently by a series of random vibration,while the simulation indication of test environment can provide reference for establishing the test condition.A simulation model was built for primary mirror component of space camera in this paper,and was solved by means of simulation analysis of random vibration.The analysis result indicated the acceleration and stress response of primary mirror component under the action of random vibration load,verified the reliability of structure design,and provided reasonable reference for dynamic environment condition in beginning stage of camera structure design.
