摘要: 针对圆锥体外表面贴装工作设计了一种串联式机械臂末端机械手。对圆锥体进行空间分析,根据圆锥体几何特征确定贴装技术方案并进行构型设计。完成机械手结构设计,利用拉格朗日法推导动力学方程,利用D-H法对正逆运动学进行求解。利用遗传算法NSGA-Ⅱ对执行器高负载零部件进行结构尺寸优化并对优化前后零部件进行有限元分析对比。通过虚拟样机、样机动态实验结果对比验证设计机械手的可行性,并分析了外界影响因素,最终证明设计的机械手可行并为其后续改进提供了方向。

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.
