摘　　要：提出了一种实用性和可操作性较强的八杆机构多目标优化方法.将设计变量矩阵分解为两组耦合度较小的矩阵,提取重要度最高的几个优化目标,把其他优化目标转换成约束条件,建立起八杆机构多目标优化数学模型,同时创建了工作装置多目标优化流程.将该数学模型加载于系统动力学分析软件ADAMS,借助该软件的内建函数,把多目标优化转换成单目标优化,实现了优化过程的函数驱动与函数监测.最终实现了工作装置的快速优化与仿真.In this study,a multi-objective optimization method,which possesses practicality and operability,is preliminarily proposed.Afterwards,the design variable matrix is decomposed into two low coupling-degree matrices to extract the critical optimization objectives.In this fashion,other optimization objectives are converted into constraints.As a result,a multi-objective optimization mathematical model,together with working device optimization procedure,is established in terms of an 8-rod mechanism.By adapting the mathematical model to the system dynamical analysis software,i.e.ADAMSTM,the multi-objective optimization is transferred to single-objective optimization via embedded functions.Eventually,the rapid optimization and simulation are realized based on functional driving and monitoring.
