摘　　要：将大转角重载荷铰链的设计问题分为两步,首先是构型设计,最后是机械设计。在构型设计阶段,选择了具有冗余特征的铰链构型,根据铰链的使用目的、机构运动条件及存在的几何约束等建立了数学模型,采用粒子群优化算法以承载能力为优化目标对铰链构型尺寸进行了优化设计。在机械设计阶段,对铰链的受力情况进行了分析,选择了电动缸、滑动轴承材料及配合关系等,最后完成了铰链的设计工作。采用该方法,获得了转角大且承载能力强的铰链,为具有类似需求的铰链设计提供了一种良好的思路。To design a joint with large swing angle and huge payload,a two-stage design method is chosen.The first stage is the mechanism design of the joint,and the next stage is the mechanical design.In the mechanism design,a redundant mechanism is chosen, and according to the purpose of the joint,and its movement conditions and geometric constraints ,the mathematical model is built,using particle swarm opti- mization （PSO）to obtain the optical mechanism with huge payload.During t analysis is applied and electric cylinder is selected to complete the joint.With designed,which offers a good idea to design the similar joints. he mechanical design,stress this method,the joint is well
