摘　　要：从防护装置与船体产生的最大碰撞力、吸能等角度,提出将钢-聚氨酯夹层结构应用到可拆卸式船桥碰撞防护装置的改进方案。对改进后防护装置在船桥碰撞过程中采用非线性有限元技术进行仿真计算,分析碰撞过程中的碰撞力、能量吸收等耐撞性指标。通过计算表明使用钢-聚氨酯夹层结构替换防护装置的外围板,提高了结构尺度利用率,在有效行程内降低了碰撞力和增加总体的能量吸收,提高了整体的碰撞性能。From the angle of the protective device＇s maximum impact force, penetration and energy absorption, the improvement design of replaceable protection device is studied by the using of steel-polyurethane sandwich. Using the nonlinear finite element techniques, with the analysis of the impact force and energy absorption crashworthiness indicators during collision, the effect of improved verification is assessed Through the replacing protection device＇s out panel using steel-polyurethane sandwich, the utilization rate is improved, the distance is controlled effectively, the body＇s impact force is slowed, the energy absorption is increased and the overall performance of the collision is improved.
