摘要

摘要: 在海洋平台、核电站、石油石化等工业中，海洋从式井组隔水管、换热器管束等在流体作用下，可能诱导管束振动过大，引起管束之间碰撞，从而导致管束失效。这是一种典型的管束振动与碰撞接触的流固耦合动力学问题。但管束与流体耦合动力学及其碰撞接触的研究成果还未见报道。该文针对管束振动与碰撞接触非线性动力学问题，以三维管束及圆筒流体域内的非定常流体为研究对象，不仅考虑流固耦合界面位移、速度协调以及载荷平衡条件，还考虑管束接触边界以及流体域耦合边界拓扑结构的改变，建立了圆筒流体域内管束振动与碰撞力学模型及算法。算例结果表明，在圆筒流体域内，弹性管束发生接触碰撞时，流体压力在管束接触点处相等，且流体在管束侧流面流动较快。

Abstract: In offshore platforms, nuclear power stations and oil fields, the marine risers and heat exchangers are liable to vibrations induced by cross flow and consequent collision between bundle tubes, and even fail in the flow field. This is a typical problem in the fluid-solid coupling dynamics of flow-induced vibration and collision. But the relevant research has rarely been reported. In view of the nonlinear dynamics problem of flow-induced vibration and collision in the tube bundle, the 3D tube bundle and the unsteady fluid in a cylinder were selected as the research objects. The consistent conditions of displacement and velocity and the load balancing were considered at the fluid-solid coupling interface. The contact boundary between bundle tubes and the change of topological structure were also studied at the interface. The mechanical model and algorithm were established for flow-induced vibration and collision between bundle tubes in the cylinder fluid. The examples show that, when the elastic tubes collide with each other, the fluid pressure is equal at the contact point, and the fluid flow faster at the side stream surface of the bundle tubes.
