摘　　要：总结了船桥碰撞分析的有限元计算基本理论框架,运用非线性有限元技术建立了船舶与桥墩的有限元碰撞模型。利用流固耦合的方法,分别分析了有无防护设施的桥墩在船舶碰撞时的能量转化、碰撞力时程变化,并对比了有无防护设施的桥墩受力情况,实现了船与桥墩、船与桥墩防护设施碰撞过程的数值模拟。The FEA basic theoretical framework of ship collision with bridge pier was summarized in this paper.The ship and the bridge pier finite element model were established by the use of nonlinear finite element techniques.By using fluid-structure interaction method,the energy conversion process and the collision force of bridge pier with protective equipment and non-protective equipment were analyzed,and the stresses of both situations were compared.Numerical simulation of the ship and bridge pier,ship and the bridge pier protection facilities collision were realized in this paper.
