用新的等效动刚度系数法对汽轮发电机组动平衡进行研究，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的残余振动，方便地找到最合适的配重。对 ２００ ＭＷ机组的成功应用证明了该方法是正确和有效的。
With the new equivalent dynamic stiffness coefficient method, the dynamic balance of steam turbine-generator set is studied. Only one time agitation of the rotor system can predict the residual vibration of each set by computer simulation to find the most suitable counterweight conveniently. The successful application of the 200 MW unit proves that the method is correct and effective.
