摘要
通过分析平面闸门垂向振动机理将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与驰振引发振动,并对两种自激振动的机理与振动稳定性进行研究,重点考察Scruton数对闸门振动稳定性的影响,提出关于Scruton数的稳定性指标,实验结果与稳定性指标相吻合。
According to the vibration mechanism,the self-induced vertical vibration of plane gate was divided into two types: flow fluctuation and fluid inertial mechanism and galloping mechanism.Vibration stability and mechanism of the two kinds of vibrations were studied respectively and the influence of Scruton number on vibration stability of gate was focused on.Two different stability indexes related to Scruton number were given based on the two kinds of vibrations mentioned above.
