    This paper presents a method for calculating the modal logarithmic decay ratio of the shaft set torsional vibration in a turbogenerator unit.This logarithmic decay ratio of the shaft set is in direct proportion to the ratio of the energy dissipated per cycle to the peak strain energy.The turbine-to -generator inertia ratio increases and the first modal logarithmic decay ratio decreases as the single unit capacity is increased,so the possibility of the shaft set torsional vibration increases.The vapor damping on the turbine shaft decreases as the unit load is decreased,so the modal logarithmic decay ratio of the shaft set torsional vibration decreases.Then,on the low load condition the possibility of the shaft set torsional vibration increases.

    本文给出了一种汽轮发电机组轴系扭转振动模态对数衰减率的计算方法.轴系扭振的模态对数衰减率正比于每个振动周期耗散的能量与峰值应能的比值.随着单机容量的增加,汽轮机的转动惯量与发电机的转动惯量之比值增加,轴系的第一阶模态对数衰减率则减小,轴系发生扭转振动的可能性则相应增大.当机组的负荷减小时,作用在汽轮机转子上的蒸汽阻尼下降,从而轴系的模态对数衰减率下降.那么,机组在低负荷的情况下,轴系发生扭转振动的可能性增大.
