以优化后的四杆机构为受控五杆机构的初始机构 ;按受控机构学原理 ,计算精确实现N点所构成轨迹的受控构件的补偿运动 ;分析受控五杆机构实现轨迹的动态误差分析 ;计入动态误差分析后调整补偿运动 ,并再次分析受控五杆机构实现轨迹的动态误差分析 ,直到实现轨迹综合误差最小 ;从而得到弹性受控五杆机构精确实现轨迹的综合方法 The optimized four-bar mechanism is the initial mechanism of the controlled five-bar mechanism. According to the principle of controlled mechanism, the compensation movement of the controlled member with the trajectory formed by point N is accurately calculated. The dynamics of the controlled five-bar mechanism trajectory Error analysis; included in the dynamic error analysis to adjust the compensation movement, and again analysis of controlled five-bar mechanism to achieve trajectory dynamic error analysis, until the realization of the trajectory of the smallest error; resulting elastic controlled five-bar mechanism to achieve an accurate trajectory synthesis method
