【摘要】 用结构设计软件SolidWorks建立某空间相机镜头的精确几何模型,在几何模型的基础上进行力学模型简化,并使用Patran建立相机镜头的有限元模型,然后使用MSC Nastran对该相机镜头进行静力分析、模态分析和随机振动分析,分析结果与试验结果误差小于5%.更多还原

【Abstract】 The precise geometric model of a space camera lens is built by structural design software SolidWorks,the mechanical model on the basis of the geometric model and establish finite element model is built by Patran,and the static analysis,modal analysis and random vibration analysis are performed by MSC Nastran. The result error between analysis and experiment is less than 5%.更多还原
