水轮发电机组切向扭转振动研究

Research on tangential torsion vibration of water turbine generator sets

本文对水轮发电机组切向扭转振动机理进行研究,将机组由于切力所引起的切向扭转振动分解成转子与转轮组成的两圆盘扭转振动和机组主轴组成轴系统的扭转振动两个系统来考虑。经过简化后,用数学方法分别推导出两系统扭转振动方程并解出振动方程解。

The paper discusses the tangential torsion vibration of water turbine generator sets. In order to study,it is divided into two vibrations of two round plates torsion system consisted of rotor and runner and torsion system of principal axis. The mathematical equation solutions of the two torsion vibration systems have been separately got.
