Other Abstract

Considering the latest developed Friction Stir Welding (FSW) robot, a set of structure design analysis process is established for large-scale equipments of heavy-loading and high precision. The FSW robot is characterized by large volume, complicated structure and extremely bad working conditions. In order to improve the accuracy and evaluate the mechanical property of the welding joints, the mechanical model of the FSW head is built and the welding process under five working conditions is simulated. The obtained forces and torques can be taken as the boundary conditions for robot strength and stiffness analyses; and the analysis results can be used to verify the rationality of structure design of the robot. Simulation results show that the stiffness performance of the robot is good under the most severe welding condition of melon-segments configuration; all the functional components are safe and reliable, and the structure design of FSW robot meets the welding quality requirement. The results may provide references for further lightweight design and mechanical performance optimization of the FSW robot.
