| 摘 要： | 针对船闸大尺寸平板输水阀门的流激振动问题，应用模态试验与有限元数值模拟相结合的分析方法研究阀门的自振特性，指导阀门结构动力优化设计，通过水弹性模型试验研究阀门的流激振动特性。研究表明：阀门自振频率的试验值和计算值吻合较好，振型完全一致；结构优化后基频显著提高，已完全脱离了水流脉动的高能区，流激振动响应较小，不至于产生危害。

| Abstract: | For the flow-induced vibration problem of the large-scale plate valve of a ship lock, we employthe method of mode test and FEM simulation to study the self-vibration characteristics of the plate valve. The resultis applied to conduct the dynamic optimization design of the structure. The hydro-elastic model test is conducted tostudy the flow-induced vibration characteristics of the valve. It is found that the test value and the calculation valueof the self-vibration frequency and the mode shape of the valve are consistent. The basic frequency is improvedobviously, which avoids the high-energy region of the flow pulsation. The flow-induced vibration response isrelatively small and will not induce harms. |
