摘要
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 ,分析受控构件的补偿运动规律 ;运用转移矩阵法 ,求解受控五杆机构具有线性时变特性的动态误差 ;调整补偿运动规律 ,再进行动态误差分析 ,直至满足精度要求 ,从而真正“精确”
The designed method of the controlled five bar elastic mechanism for realizing the given function is established, the four bar mechanism having been optimized is used as the initial mechanism of the controlled five bar mechanism.The law of compensation movement of the controlled links is analysed according to the principle of the controlled five bar mechanism.The dynamic error of the variable character of the controlled five bar mechanism(when it possesses linearity) is found.The the dynamic error is analysed again by adjusting the law of compensation movement until the requirement of accuracy is met, thus the given function is really' accurately' realized.
