Abstract: The finite element analysis of the sorting device is to simulate the real physical system by means of digital approximation, which can accurately predict the performance of the sorting device and shorten its development cycle. According to the required body structure and performance re-quirements, the overall design scheme and the structure of the manipulator are established. The stress and displacement cloud charts and static stiffness of the manipulator are analyzed by the turntable sorting device. The top ten-step natural frequency and main vibration type, as well as the displacement curve of a node at the end of the manipulator with the modal change are obtained, which provide the theoretical basis for the further optimization design of the weak dangerous link.
