Ship collision often takes place under the severe sea conditions.In fact,collision process is the coupling of contact force and external environmental load.Based on the non-linear finite element method,ship collision model considering the effect of wave is built,and the collision process is simulated numerically.The results of collision under conditions with or without wave are compared and the influence on side structure by the wave heights and incident angle of the wave is analyzed.The results of simulation indicate that wave has negative effects on ship collision,and some guidance and suggestions are given from the viewpoint of engineering.%船舶碰撞多发生在一些比较恶劣的海况下，事实上碰撞过程是碰撞作用和外部环境荷载作用的耦合。基于非线性有限元方法，建立了考虑波浪作用的船舶碰撞模型，对碰撞过程进行了数值仿真模拟。将有无波浪存在下的碰撞结果进行了对比，并分析了波浪波高以及波浪入射角度对被撞船舷侧结构的影响。结果表明，在一定情况下波浪对碰撞过程有不利的影响，并从工程角度给出一些指导建议。
