摘要
望远镜是天文观测的重要工具,其口径越大则分辨能力越高,分辨能力的大小又决定了人类可观测到的宇宙空间的大小。相较于传统的地基大口径望远镜,车载望远镜对天气和环境有着更强的适应能力,观测更高效。车载这种动态形式对望远镜的整体质量和尺寸有着严格的要求,随着望远镜口径的增大,望远镜质量也会呈几何倍数增长,这对载车平台的结构也提出了更高的要求。该文以大型光学望远镜的载车平台为研究对象,通过将不同的设计方案进行有限元分析对比,从而得到较好的载车平台结构,以满足望远镜口径增大对载车的要求。
Telescope is an important tool for astronomical observation,and the larger the aperture,the higher the resolving power,which in turn determines the size of the universe that can be observed by humans.Compared with the traditional ground-based large-aperture telescopes,the vehicle-mounted telescopes are more adaptable to weather and environment and more efficient in observation.Vehicle has strict requirements on the overall quality and size of the telescope;as the aperture of the telescope increases,the mass increases geometrically,and the structure of the vehicle-mounted platform is also more demanding.In this paper,the carriage platform of a large optical telescope is studied,and different design solutions are compared with each other through the finite element analysis to obtain a better carriage platform structure so as to meet the requirements of the increased telescope aperture for the carriage.
