摘　　要：采用Spalart-Allmaras湍流模型模拟流体运动情况,建立了弯管和流体的有限元模型;用ADINA对阀门开启过程中流体冲击导致的弯管振动现象进行流固耦合仿真分析,分析了3种不同流速下的弯管振动情形,并绘制了相关节点的位移-时间曲线。结果表明:随着弯管内流体流速的增大,弯管所受应力增大,弯管振动也越激烈。Spalart-Allmaras turbulence model was used to simulate fluid motion. The finite element models of the fluid and elbow pipe were built. In the valve opening process, it was analyzed on the fluid structure interaction of fluid impact pipeline vibration phe- nomenon. The elbow pipe vibration under three different flow velocities was studied, and the correlative node displacement-time curves were drawn. The results show that with the flow velocity of the fluid in elbow pipe increasing, elbow pipe stress increases, the elbow pipe vibration is more intense.
