摘要

摘要: 从大射电望远镜馈源舱AB轴机构转动装置的结构出发,分析目前AB轴机构设计中驱动力矩过大的原因,完成AB轴机构转动装置的优化设计。在目前AB轴机构的结构设计基础上,从A轴、B轴驱动的负载力矩出发,对A轴、B轴的转动装置进行了结构优化,重新设计了转动中心的位置,通过有限元仿真分析,得出了优化前后AB轴机构的结构变形。结果表明:优化后AB轴机构的最大变形量较改进前有所减小。

Abstract: Aiming at the rotation device of the AB shaft mechanisms in large radio telescope feed cabin, we analyzed thereasons of large driving torque on AB shaft. Based on the design of the AB shaft mechanisms, starting from driving torqueof A shaft and B shaft, the position of rotation center was redesigned and achieved the optimal design of the rotationdevice of AB shaft mechanisms. The deformations of the AB shaft mechanisms before and after optimal design areobtained, respectively, by finite element analysis. The results showed that the maximum deformation of the AB shaftmechanisms was reduced, and the effectiveness of the optimal design was verified. The study provides a significantreference for the optimal design of the AB shaft mechanisms.
