主镜是望远镜系统的重要组成部分之一。随着其口径的不断增大,望远镜的重量也随之加大,自重、热变形等问题将对主镜镜面的面形精度产生一定的影响.因此,在保证系统精度的同时,要尽可能的减少结构重量,所以在设计阶段就要根据光学系统的技术要求及影响因素对主反射镜的支撑方案进行综合考虑和全面分析,使其结构设计更为合理.根据大口径望远镜系统主镜结构设计的要求,利用结构分析软件,建立结构分析模型,来确定主镜支撑方案.详细分析了大口径望远镜主镜支撑的各方面技术。
The primary mirror is one of the important components of the telescope system. As its caliber increases, the weight of the telescope will also increase, weight, thermal deformation and other issues will have a certain impact on the primary mirror surface accuracy.Therefore, to ensure system accuracy at the same time, as far as possible Therefore, it is necessary to consider and analyze the supporting plan of the main reflector according to the technical requirements and influencing factors of the optical system at the design stage, so as to make the structural design more reasonable.According to the structure of the main mirror of the large-aperture telescope system Design requirements, the use of structural analysis software, the establishment of structural analysis model to determine the main mirror support program.A detailed analysis of the large aperture telescope main mirror support all aspects of technology.
