论述了折转部件静态分析和模态分析的目的和内容,应用有限元分析软件MSC.Nastran对光谱相机折转部件进行了仿真分析。针对反射光线的偏移量进行了静态分析,验证了结构设计的合理性;模态分析计算了结构的固有频率和振型,对减振方案的实施提供了指导,为相关动力学的分析提供了数据支持。
The purpose and contents of the static analysis and modal analysis of turning parts are discussed. The simulation analysis of the turning parts of spectral cameras is carried out by using the finite element analysis software MSC.Nastran. The static analysis of the offset of the reflected light verifies the rationality of the structural design. The modal analysis and calculation of the natural frequency and mode shape of the structure provide guidance for the implementation of the vibration reduction scheme and provide the relevant dynamic analysis Data support.
