宽覆盖多光谱CCD相机模装及模态分析

CAD Molding and Modes Analysis for the Structure of Wide-swath Mutilspectra CCD Camera

文章以结构设计软件AutoDesk Inventor对宽覆盖多光谱CCD相机结构进行精确造型、模装,进行了干涉检查。应用大型结构分析软件PATRAN、NASTRAN,建立了该相机超大规模有限元模型,完成了该相机的模态分析,得出了该相机相应的固有频率和模态,验证了相机结构设计的合理性。

In this thesis an accurate molding and mock-up of the camera structure is using the structural design soft of AutoDesk Inventor. Based on a precise CAD model, an interference examination is carried through.The superlarge scale FEM model of the camera is established using PATRAN and NASTRAN. The modal analysis of the camera is accomplished and obtained validate the rationality of the structural design of the camera.
