A revised formula for calculating the stability thresholdspeed of turbine-generator bearings is presented.
对现用的汽轮发电机组轴承失稳转速的计算公式进行了修正，提出了修正公式。
2
The torque fluctuation on the higher speed shaft influences the rattling thresholdspeed more greatly than on the lower speed shaft.
低速端的扭矩波动对系统拍击门槛转速影响较小，而高速端的扭矩波动对拍击门槛转速影响较大；
