摘要

对汽轮机组轴系扭振模型模化及当量参数的计算进行了比较深入的分析，给出了轴系模型当量惯性参数及刚性参数的计算，并对国产３００ＭＷ机组轴系进行模化，得到多质量块集中质量模型。经过分析和试算，提出一种快速、有效的模型简化方法，并应用该法对国产３００ＭＷ机组轴系多质量模型进行有效合并。最后通过对当量模型扭振特性的分析计算，证明模型当量参数的计算式是正确的，提出的模型合并方法为轴系扭振模型简化提供了一个有效的途径

Abstract

A systematic study is made on establichment of torsional vibration model of turbine generators and on the calculation of the equivalent parameters in this paper.The most effective method of model simplification is also proposed after comparison and trial calculation.Through the calculation of model parameters and vibration properties of domestic 300 MW unit

it is proved that the proposed method is feasible and effective.
