摘要
望远镜是动态光电跟踪探测系统中的关键部件之一,特别是大口径光学系统,不仅要求主望远镜的稳定性高,还要尽可能地减少结构质量。根据1.3m大口径望远镜的结构设计方案,利用大型有限元结构分析软件I DEAS,采用板壳和质量单元描述结构主体,建立了较为精确的结构分析模型,求得了望远镜在不同俯仰角位置时的主、次镜位置变化,为整个望远镜的结构设计提供了可靠的依据。
Telescope is one of the most important components of dynamic photoelectric acqui sition and tracking system, especially for the large-aperture system, which sho u ld have not only high stability but also light self-weight. Finite element mode l for the 1.3 meter large-aperture telescope is built by shell and mass elements , according to the design proposal and using large-scale finite element analysis software I-DEAS. Deviation results of primary and secondary mirror with differe n t pitching angles are calculated, which provide reliable datum for designing the whole telescope.
