摘要
作为一种常用挡水构件,闸门被广泛的应用在各种挡水建筑物中,因此它的安全性关乎人民的生命和财产安全。闸门在全部或局部开启时,往往会发生振动,有时甚至在关闭蓄水时也会产生振动。因此,闸门的动力特性以及与其相关的闸门动力响应和动力稳定问题,是水工结构工程中亟待解决的一个重大问题。针对某水利工程中实际应用到箱形结构闸门用AN-SYS进行自振分析,并讨论在两种约束情况下的闸门的振型,以此获得数据分析此闸门在运行过程中是否安全。
Sluice gate is wildly used in various water-retaining Structures, it is of great importance to the life and property safety of the people.when the gate is fully or partially opened ,the vibration would occurs at the gate, even at the situation of closing the gate for water storage. Therefore, the dynamic characteristics and its corresponding response as well as the dynamic stability are signifi- cant problems which need urgent solution in hydraulic structure engineering. The self-vibration of one sluice gate in practical project is analyzed by using FEM software ANSYS. The results of vibration mode under two kinds of constraints are discussed. The data ac- quired from the FEM analysis is used to check whether the sluice gate is safe or not during its working period.
