摘要
以两自由度可控连杆机构系统为研究对象,在所建系统机电耦合动态模型的基础上,考虑了系统结构参数和控制电机的电磁参数对连杆中点的动态响应的影响。针对系统预定圆轨迹下的动态响应,建立了参数优化数学模型。采用基于混沌的粒子群优化算法,实现了系统动态性能优化。
A hybrid five--bar linkage mechanism system was investigated. Based on the electromechanical coupling dynamic model of the system established by the finite element method,the effect on the dynamic response of structural parameters and electromagnetic parameters of the system was con- sidered. And based on the dynamic response on condition that the output trajectory was circle, a parameter optimal model for the system was established by chaos--based particle swarm optimization method. Then the dynamic characteristics of the system were optimized. This paper provides theoreti- cal direction for the optimum control of such kind of multiple--degree--of--freedom linkage mechanism systems under given trajectory.
