提出用动刚度系数方法对转子和轴系残余振动进行预测。对转子系统只需一次加重便可通过微机模拟预测出各组配重时的残余振动，可以方便地找到合适的成组配重。该方法在实际应用中获得了很好的效果。
The method of dynamic stiffness coefficient is proposed to predict the residual vibration of rotor and shaft system. The rotor system only needs to be aggravated one by one to predict the residual vibrations of each group of counterweights by computer simulation, so that the suitable group of counterweights can be conveniently found. This method has got good effect in practical application.
