摘　　要：分别运用封闭矢量多边形投影法、复数矢量法及矩阵法,对闭链二自由度平面五杆机构进行了运动学特性分析,推导了运动学正解方程,比较分析了各方法的求解特点和应用场合,通过混合驱动五杆机构的算例,验证了运动学方程的正确性。采用Solid Works软件模拟了原动件初始位置变化对输出轨迹的影响,得出了运动学方程与轨迹输出的内在联系,为混合驱动机构的运动学特性解析法求解提供了参考。The kinematics characteristic of the closed chain two degree of freedom planar five-bar mechanism is analyzed by using the closed vector polygon projection method,complex number-vector method and matrix method.The kinematics equations are deduced,furthermore,the characteristic and application situations of each method are compared and analyzed.The kinematics equations are validated according to the example designed.By using the Solid Works motion simulation software,the motion path is changed with the original position of driving link,and the inner link between kinematics equations and output motion path is achieved.The reference for solving kinematic characteristic of hybrid driven mechanism in analytic method can be provided.
