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 key components in the dynamic photoelectric tracking detection system. Especially the large-aperture optical system not only requires the stability of the main telescope but also reduces the structural quality as much as possible. According to the structural design of 1.3m large aperture telescope, a large finite element structural analysis software I DEAS was used to describe the structure main body by using the shell and the mass element, and a more accurate structural analysis model was established. At the different elevation positions of the telescope, Main and secondary mirror position changes for the entire telescope structural design provides a reliable basis.
