摘　　要：以对称叠层复合材料构件的机构系统非线性动力学模型为对象,研究弹性连杆机构动态性能优化设计,采用了直接积分法-Newmark算法计算连杆中点的位移响应,并针对连杆中点的最大振幅建立最小优化模型;根据此模型具有非凸、多峰值的特点,运用混沌微粒群算法对此模型进行优化。结果表明,能够获得较满意的优化结果,能使系统的动态性能得到了较大改善,为解决此类优化问题提供了有益的尝试,对实际工程应用也有一定的指导意义。Base on the nonlinear dynamic model of symmetrical terrace composite material component system, this paper discussing the optimal design of flexible link mechanism＇s dynamic properties. By ways of immediate integration-Newmark author calculate the response displacement on midpoint of link mechanism and create minimum optimal model according to the maximal swing of midpoint. As this model have the characters of none protuberant and multi-peaks, author optimize the model by ways of algorithm chaos particulate group . Result of optimize is satisfaction, dynamic properties of system is improved greatly .This paper provide the solution to such kind of optimize problem, it is valuable to engineering application.
