摘要
水电机组水导支撑系统模向刚度的计算分析是机组轴系振动分析的关键技术问题。本文将水导支撑系统分为导支撑组合结构及轴承油膜两部分,系统地阐述了这一问题的理论分析方法,并给出了计算实例。
The calculation and analysis of lateral rigidity of turbine bearing supporting system are the key technical problem for vibration analysis of hydrogenerating set shaft system. In this paper the turbine bearing supporting system is divided into bearing supporting structure part and oil film part, theoretical analysis of this problem is systemetically presented and calcalation example is given.
