This paper presents a method for calculating the modal logarithmic decay ratio of the shaft set torsional vibration in a turbogenerator unit.

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。

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.

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。

All the machines were set up along the shaft, with a belt giving each of them power.

所有的机器都靠这个轴带动。
