采用完全水弹性相似模型试验的方法,对巴基斯坦汗华水电站表孔弧形闸门的流激振动情况进行了研究.动力响应试验结果表明:大弧门和舌瓣门的自振频率均避开了水流脉动压力高能区,运行中可避免因振动频率相近而引发的自激振动.另一方面,闸门振动加速度的大小与止水设置情况密切相关,在闸门运行过程中,应尽量避开加速度最大和动应力最大的工况. The full hydroelasticity similarity model test is used to study the flow induced vibration of the surface arc gate of Khanwah Hydropower Station in Pakistan.The dynamic response test results show that the natural frequencies of the large arc gate and the flapper gate are avoided In the operation, the self-excited vibration caused by the similar vibration frequency can be avoided.On the other hand, the magnitude of the gate vibration acceleration is closely related to the setting of the water stop, and the maximum acceleration should be avoided during the operation of the gate And dynamic stress the largest working conditions.
