Analysis of lifting system of FAST feed receiver robot

This research mainly focuses on the analysis of the lifting system of the FAST receiver robot. The deformation will appear after loads are added to the spatial mechanism; and this will further affect the smooth operation of the mechanism. The finite element method is applied to the lifting system of the FAST feed receiver disassembly and handling robot; the stress and deformation distributions of the lifting system under rated working conditions can thus be analyzed and related results have also been obtained. The resultant results provide references for the actual performance of the lifting system. The results also reveal that the maximum deformation as well as the stress meet the predetermined requirements of the lifting system.
