摘要
目前水工建筑物流激振动的研究方法主要有原型观测、模型试验及数值分析法,笔者应用流固耦合理论采用三维有限元法对流激振动进行了数值模拟研究,分析成果与原型观测成果相统一,验证了研究方法的可行性,可为后续类似工程分析提供参考。
The study methods of the flow-induced vibration of hydraulic structures typically include prototype observation, model test and val- ue analysis. In this paper, the fluid-solid coupling theory and 3D finite element method are applied for the value simulation study on the flow -induced vibration. The study results are in compliance with those of the prototype observation. This verifies the feasibility of the study method. It provides analysis of the similar projects in the future with reference.
