摘要

摘要：本文通过分析平面闸门垂向振动机理把平面闸门垂向自激振动分为两类：流量系数及流体惯性引发振动和驰振引发振动，分别对两种自激振动的机理和振动稳定性进行研究，重点考察了Scruton数对闸门振动稳定性的影响，最后分别对两种自激振动提出了关于Scruton数的稳定性指标，实验结果与稳定性指标相吻合。

Abstract

The paper divides self-induced vertical vibration of plane gate into two types: flow fluctuation and fluid inertial mechanism and galloping mechanism based on the vibration mechanism. Vibration stability and mechanism of the two kinds of vibration are researched in which the influence of Scruton number to vibration stability of gate is focused on. Finally two different stability indexes related to Scruton number is given based on two kinds of vibration.
