摘　　要：多杆机构设计工作的主要部分是杆长和节点坐标等基本结构参数的确定。用传统的方法设计多杆机构,设计时间长,工作量大,而且设计结果不一定是最优的设计。文中建立多杆机构优化设计的数学模型,并且将多杆机构的基本结构参数(杆长、节点坐标)作为设计变量,将体积最小化和功率最小化作为目标函数,运动连续性和空间尺寸等要求作为设计约束条件,运用MATLAB编制多杆机构优化设计程序,可以方便快速地计算出符合设计要求且体积功率最小的多杆机构。The main part of multi bar mechanism design is to determine the length of link and node coordinates of basic structural parameters,design of multi bar mechanism with the traditional method,the design time is long, heavy workload,and the design result is not necessarily the optimal design. A multi bar mechanism optimization design model is built,the basic structural parameters（length,node coordinates） are taken as the design variables,the volume minimization and power minimization are taken as the objective function, the motion continuity and spatial size requirements are taken as design constraints, MATLAB is used to compile multi bar mechanism optimization design program to calculate multi bar mechanism,which can meet the design requirements and realize the smallest volume power.
