摘要

本文所述机器人用于运送FAST馈电接收器;其升降部分为空间多杆机构;为了在运输中实现准确定位，避免大载荷引起的变形从而影响机构的正常工作，整个机构需要具有良好的刚度。为了分析这种复杂机械机构的刚度，可以采用有限元法进行仿真。基于Abaqus有限元软件，对搬运机器人，特别是其升降系统在额定工况下的应力和变形进行了分析;得到了提升系统关键部件的应力和整体变形。分析结果表明，提升系统的最大应力和最大变形均未超过预定目标。所得分析结果为提升系统的实际性能提供了重要参考。

FAST Handling Robot Stiffness Analysis Based on Finite Element Simulation

The robot described in this paper is used to transport the FAST feed receiver; its lifting part is a spatial multi-bar mechanism; in order to achieve accurate positioning in the transport and avoid deformation caused by large load and thus affecting the normal operation of the mechanism, the whole mechanism needs to have good stiffness. To analyze the stiffness of such complex mechanical mechanism, finite element method can be used for simulation. Based on Abaqus finite element software, the stresses and deformations of the handling robot, especially its lifting system, were analyzed under rated working conditions; the stresses and overall deformations of key parts of the lifting system were obtained. The analysis results showed that the maximum stress and deformation of the lifting system did not exceed the predefined targets. The obtained analysis results provide an important reference for the actual performance of the lifting system.
