摘要:
水工建筑物由多个部分组成,而闸门是其中非常重要的组成部分,负责关闭和调节孔口,是一种可活动式结构,可以用来挡水,对上下游水位以及过闸流量进行调节,实际水利工程实施过程中存在闸门振动问题。根据实际工程中存在的问题,针对江苏省秦淮新河水利枢纽节制闸,对闸门在流固耦合的作用下进行平面力系简化计算和有限元静力计算,研究干、湿模态下闸门的相关特性,分析闸前有水时,因水体与闸门的耦合作用,导致闸门振动频率的规律和振动的响应关系,以提高水工闸门运行中的稳定性。
Abstract:
Hydraulic structures are composed of many parts, among which the gate is a very important part, it is responsible for closing and adjusting the orifice, is a movable structure, can be used to block water, adjust upstream and downstream water level and the flow through the gate. But in the actual water conservancy project implementation process, there is always a gate vibration problem, and has not been completely solved. According to the problems existing in the practical engineering, aiming at the control gate of the Qinhuai Xinhe Water Control Project in Jiangsu Province, the simplified calculation of the plane force system and the finite element static calculation of the gate under the action of fluid-solid coupling are carried out. The relevant characteristics of the gate in dry and wet modes are studied, and when there is water in front of the gate, the coupling effect of the water body and the gate leads to the law of vibration frequency of the gate and the response relationship of vibration, so as to improve the stability of the hydraulic gate in operation.
