摘　　要：从平面连杆机构的闭环矢量方程出发,介绍了求解平面连杆机构位置问题的牛顿迭代法.通过对典型平面连杆机构的分析,说明其在机构运动分析中的具体应用方法,并给出相应实例验证该方法的有效性,同时还介绍了机构运动分析中迭代初值的计算方法.Based on closed-loop vector equation of planar linkage mechanism, Newton method is introduced this paper for solving position problems of these mechanisms. By analysis of representative mechanism, some examples are given to demonstrate the validity of Newton method in kinetic analysis of mechanisms. Finally a new method of computing initial guess of Newton method in kinetic analysis of mechanisms is described.
