摘　　要：把平面连杆机构用"基本坐标"和"连杆约束"表达为最小二乘问题,通过求解非线性方程组的形式对连杆机构的几何约束进行求解,并采用可视化搭建结果和仿真状态结果作为迭代初值,很好的解决了一般方法对迭代初值的敏感性。最后在Matlab/GUI平台上开发出通用的仿真软件,并给出了几种常见连杆机构的仿真结果。A method for expressing planar linkage with Leastsquare was presented,based on the concepts of 'Basic Coordinates' and 'Link Constraint Equations'. So the geometric constraint solving was transformed into nonlinear equations solving and improved initial value sensitivity by setting visualization constructed results and simulated results as the initial value.Finally,a general planar linkage simulation software based on Matlab/GUI is developed,and several examples are presented to show the simulation results.
