摘　　要：针对摆线液压马达优化修形的问题,提出一种以总效率为目标函数的基于粒子群算法(PSO)的优化修形方法。以某型号摆线液压马达为优化对象,建立了摆线针轮行星机构的容积效率、机械效率及总效率的数学模型,并以总效率为目标函数,对其使用PSO进行优化搜索最优修形值。结果表明,该方法可以使效率达到98.55%,比传统优化方法提高4%。Aiming at the problem of optimized modification of the cycloid hydraulic motor,it proposes a method with the objective function of total efficiency. Based on PSO algorithm,it takes a type of model as object,establishes the mathematical model of the volume efficiency,mechanical efficiency and total efficiency of the mechanism of cycloid pin gear epicycle. Taking the total efficiency as the objective function,it uses PSO algorithm to obtain the best modification values. The result shows that the method can make the total efficiency reach98. 55%,improve 4% than the traditional optimized method.
