溢流式水电站厂房结构动力特性研究
Study on dynamic characteristics of overflow hydropower house structure
【摘要】 本文以蜀河水电站厂房为例探讨溢流式厂房结构的动力特性,建立蜀河水电站厂房结构大型有限元计算模型,对厂房各部位的自振特性进行全面的分析;根据泄洪表孔水力学试验测得的脉动水压力,进行水力激振作用下的厂房结构动力时程分析,研究厂房结构的动态响应。计算研究成果为厂房结构优化设计和改进抗振特性提供理论依据。
【Abstract】 The dynamic characteristics of overflow of hydropower house structure is discussed with an example of Shuhe hydropower station.A large-scale finite element model of Shuhe hydropower house is built in this paper to calculate the self-vibration characteristics of each part of the hydropower house.Time process analysis is done for the house structure under hydraulic exciting force according to hydraulic experiment data in the surface outlet hole.This research reflects the dynamic response of the house structure and provides the theoretical basis for optimizing the dynamic characteristics of the house structure and improves its design.
【Key words】 hydraulic structure; dynamic response; time process analysis; overflow hydropower house; self-vibration frequency; hydraulic exciting vibration;
