摘要
建立了岩滩水电站厂房下部结构大型有限元模型,对发电机层楼板的自振特性做了较准确的计算;同时将机组水力激振作用下的厂房振动简化为简谐振动系统,进行了厂房结构动位移及振动速度的动力响应分析,数值计算结果与实测数据符合较好。
In this paper a largescale substructure finited element model of Yantan hydropower house was built to accurately calculate selfvibrating characteristic of generator floor. A harmonic vibration model was proposed to analyse dynamic response of the house structure from hydraulic exciting force of hydraulic generator sets. The numerical results agree well with the surveyed data on the spot.
