摘要
基于任意拉格朗日-欧拉法,描述了靠泊船与浮式码头碰撞过程中流固耦合关系。采用耦合法建立了浮式码头与靠泊船碰撞的仿真模型,真实模拟了船舶与浮式码头碰撞的过程,并与试验结果进行对比。由此可知,靠泊船碰撞对于浮式码头的运动响应、连接器所承受载荷、锚缆张力影响较为显著,流体区域也将产生较强的扰动,在实际工程应用中应加以注意。同时,也证明任意拉格朗日-欧拉法在流固耦合的研究领域优势明显。
Based on the Arbitrary Lagrange Euler method, coupling relation between structure and fluid has been described. Using the tough coupling method, the simulation model of collision between floating pier and berthing ship is established and collision has been simulated factually. From the results, we know that the collision between ship and floating pier has much effect on motion response of floating pier, loads on connectors and tension forces, and that strong move will appear in the liquid. The results also testify that Arbitrary Lagrange Euler method has advantage in the domain of coupling between structure and fluid.
