水工钢闸门振动现象及振动特性分析

Hydraulic Steel Gate Vibration Phenomenon and the Vibration Characteristic Analysis

钢闸门是水工建筑物中的关键结构，从目前闸门失事调查的结果显示，造成事故发生的主要原因是由于振动造成。振动常常出现在闸门启动、关闭两种形式下，对于闸门的正常使用有着较大的影响。为了避免振动带来的不良影响，现从闸门振动的自身特点出发，具体分析了闸门振动的振源与应对措施。

The hydraulic steel gate is crucial for building a structure parts from the gate, the investigation results showed that the main reason of the accident of the gate was the vibration. Vibration often appears during close and open the gate, which was great influence the normal use of the gate. In order to avoid the ill effects of vibration, this article analyzed the source and the gate vibration measures from the gate vibration characteristics.
