摘要
人字闸门作为一种承受单向水头的平面闸门,在通航建筑物中得到了广泛的运用。针对人字闸门在运行过程中容易出现振动现象的问题,对人字闸门进行了流激振动响应分析,以了解人字闸门外部激振作用。通过模拟水流脉动荷载,计算分析了人字闸门的应力、位移和加速度响应值,对闸门的振动危害进行了判断。
Miter gate, as the plane gate which bears one-way head, has been widely used in navigation buildings.Pointing at the problem of vibration in the operation of miter gate, this paper studies the flow-induced vibration response to understand the miter gate excitation by the external causes. Water flow pulsating load is simulated to calculate the stress,displacement and acceleration response,and judge the harmfulness of vibration.
