摘　　要：建立货船简化模型与桥墩之间正面碰撞有限元模型,并对撞击的全过程利用非线性有限元分析软件MSC.DYTRAN软件对3 000吨内河货船和九圩港大桥建模,进行仿真分析计算,研究碰撞过程中结构损伤情况、碰撞力和能量变化.研究碰撞过程中船桥之间碰撞力的变化、能量转换以及结构损伤变形情况.The finite element model of the frontal collision between the simplified model of the cargo ship and the bridge is established. The whole process of the impact is modeled by the nonlinear finite element analysis software MSC. DYTRAN for the modeling of the 3 000 tons of the cargo ship and the Jiuwei Harbor Bridge. The simulation analysis is carried out to help figure out the structural damage, collision and energy change during collision. The changes of the collision force, the energy conversion and the structural damage deformation during the collision process are studied.
