摘要
水工闸门系统的振动严重时会造成水工闸门系统的破坏和临近构筑物的破坏。以某水电站泄洪洞中的一扇弧形钢闸门为研究对象,以模态分析确定闸门的动力特性为基础,运用流固耦合理论,附加质量法对其进行水体脉动压力作用下的动力响应分析,为水工弧形钢闸门的设计提供参考。
When the vibration of hydraulic gate system is serious,it will destroy the hydraulic gate system and destroy nearby structures. Taking a steel arch gate in tunnel spillway in a certain hydropower station as the research object,based on the dynamic characteristics of the gate through modal analysis,the dynamic response analysis of fluctuating pressures by the water are carried out by using the fluid solid coupling theory and the additional mass method. It can provide reference for the design of hydraulic arc steel gate.
