摘要
针对某拱形闸门的流激振动问题,结合水弹模型试验结果,利用ANSYS软件对闸门不同工况下的流激振动特性进行了数值模拟研究,得到了闸门不同工况下应力和位移数据,计算结果同模型试验成果吻合较好。同时,对拱形闸门的安全进行了分析,并提出了相应的建议。
Aiming at the problem from the flow-induced vibration of an arch gate,a numerical simulation is made on the characteristics of the flow-induced vibration of the gate under various operation conditions with ANSYS,and then the relevant data of the stress and displacement of the gate are obtained; from which the calculation result is better coincided with that from the model test. Meanwhile,the safety of the gate is analyzed and the corresponding suggestions are put forward as well.
