摘　　要：提出了解决机构摆动力矩完全平衡的一种新方法——机构摆动力矩完全平衡有限位置法,给出了机构摆动力矩完全平衡的一般方程,并例举了铰链4杆机构摆动力矩平衡的具体求解。该方法易于自动生成平衡条件方程,不需进行复杂的公式推导,对于有解析解或数值解的机构均适应,只需知道机构在运动过程中的(v+f+1)个位置上的角位置及角加速度,就可用有限位置法对其进行摆动力矩的完全平衡,与质量矩替代法相比较,不需进行连杆的附加配重计算。A novel method for balancing the shaking moment of a mechanism is presented, and it is called the finite place methid. It is a straightforward way to solve the shaking moment equilibrium. The balanceable condition equation groups were deduced automatically, so the deduction of the balance.able formula was not needed. This method is suitable for the mechanisms with analytical or numerical result. If the angle positions and the angle accelerations of the mechanism on its （ v ＋ f ＋ 1 ） movement positions are known, then the complete shaking moment of this mechanism can be solved using the finite place method. Compared with the mass square method, the calculating of the additional mass of the linkage is no longer needed in the solving process of the moment square equilibrium by using the finite place method.
