| 摘 要： | 针对平面连杆运动位置数多于确定机构的精确点数的运动综合问题，提出运用最小误差为目标函数的参数辩识法算法。通过分析典型的平面四连杆机构的非线性解析方程，根据给定的位置，分解方程，构建线性方程组，引入最小误差目标函数和伪逆的处理方法，得出最优的参数值。通过例证说明该算法的正确性、通用性和有效性。

| Abstract: | Algorithm based on parameter identification by building goal function of least error is proposed for synthesis of planar mechanisms on the context of number of prescribed positions are greater than the maximum a linkage can generates precisely.Nonlinear holomorphy equations of planar four-bar linkage is analyzed to form linear equations by decomposing nonlinear equations Based on the prescribed positions.The optimal parameters is derived through goal function of least error and pseudo-inverse resolution.Illustration shows the correctness,versatility and validity of algorithm. |
