Finite element analysis of humanoid robot arm

Abstract

Considering the problem that the 18 DOF humanoid robot's joints connect with others part is weak. The finite element analysis is adopted to analyze the reasons why the connection of human robot's joints with others is weak. First of all, the 3D model of humanoid robot arm is set up on the SolidWorks; Secondly, the shoulder joint and elbow joint of the humanoid robot arm 3D model are applied to the constraints respectively in the workbench ANSYS, The humanoid robot arm will be research in the platform, including structural static analysis and modal analysis. Finally, the weak parts are exposed in the analysis results and the reasons are analyzed. In accordance with the consequence of the modal analysis of the humanoid robot arm, the corresponding modal frequencies are obtained and the potential dangerous source of the robot arm is pointed out. The study provides the theoretical basis for the optimization design of the arm structure of the humanoid robot, and the selection of parts materials.
