基于ANSYS的平面闸门流固耦合振动特性的有限元分析
Finite Element Analysis on Natural Dynamic of Fluid-solid Coupling Vibration of Plane Gate Based on ANSYS
摘要
Abstract
Against the background of the vibration problem of the plane gate in the inverted siphon exit of the large-scale hydraulic project in Northern Xinjiang,the natural vibration characteristic of the plane gate was studied using ANSYS. The entity model and finite element model were built. With the fluid-solid coupling,the natural characteristics of the gate with or without water condition were analyzed. The first six natural frequencies and their vibration modal shapes of the gates were calculated. The result showed that the water height has a significant impact on the natural frequencies of the plane gate.the first natural frequency was reduced to 28.5% and the structure of the plane gate must be improved.关键词
