A model of ship side collision is built with ANSYS/LS-DYNA for studying the effect of different impact positions and initial velocities on side structure. Based on the results of simulation, collision force-displacement curves, energy absorbing-displacement curves and the deformation of ship structure are obtained. The study indicates that the change of striking ship's impact position and initial velocity will cause different form and extent of deformation of struck ship. The critical velocities of hull shell damage are determined, which can be a theoretical basis for ship design.%通过ANSYS/LS-DYNA对船舯碰撞进行建模,重点研究撞击位置和初速度改变对被撞船舷侧结构的影响.经仿真计算,得到了碰撞力和吸能随碰撞船位移变化的曲线以及在极限撞深下舷侧结构的损伤状态.结果表明,碰撞船撞击位置和初速度的改变会对被撞船舷侧结构带来不同形式和程度的损伤变形.此外,还确定了船壳破损的临界速度,可为船舶设计部门提供理论依据.
