| Abstract: | A series manipulator end-effector was designed for cone surface mounting. Firstly, the space analysis of the cone was carried out. According to the geometric characteristics of the cone, the mounting technology scheme was determined and the configuration design was obtained. Secondly, the structural design of the manipulator was completed. Lagrange method was used to derive the dynamics equation, and D-H method was used to solve the forward and inverse kinematics. Then, NSGA-Ⅱ genetic algorithm was used to optimize the structural dimensions of the high-load parts of the actuator, and the finite element analysis of the parts before and after optimization was compared. Finally, the feasibility of manipulator was verified by comparing the results of virtual prototype and prototype dynamic experiments, and the external influence factors were analyzed. The feasibility of manipulator was proved and the direction for the subsequent improvements was provided. |
