摘　　要：介绍了空间遥感仪器中卡塞格伦镜筒的结构设计,利用三维CAD技术构建了产品模型。针对主镜筒的轻量化问题,设计了几种结构方案,利用CAE有限元力学分析对设计方案进行选择和评价,最后通过对整个装配体的静力学分析和模态分析考察了结构的整体性能。The design of the structure of Caseegrain drawtube in space remote instrument was introduced. The product model was constructed using 3-D CAD technique. To reduce the weight of the drawtube, 4 schemes of structure were presented. Selection and estimation of the schemes was given through mechanics analysis by CAE technique. In order to evaluating the performance of the structure, the static and mode analysis of the whole assemble structure were also carried out in the end.
