航空光谱相机折转部件的有限元分析
Finite element analysis of optical turning reflector in an aerial spectral camera
【摘要】 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。
【Abstract】 Purposes and contents of static and model analysis are stated.With the use of the finite element analysis software MSC.Nastran,emulational calculation of the turning and reflecting component of an aerial spectral camera is performed.Through the static analysis results the design of the component ’s structure is proven to be correct;by means of model analysis,the features of the component are acquired,the results have great impact on the practical use and play an important role in the relevant dynamic analysis of the component.
