摘　　要：研究碰撞载荷作用下加筋板架的动态响应对于深入理解船舶碰撞力学机理和开展船舶耐撞性结构设计具有重要的指导意义。基于最近国外加筋板架碰撞模型系列试验结果,应用数值仿真的方法对其中5种典型加筋板架进行计算分析,得到不同加强筋情形下板架的动态响应特征,并从损伤变形模态及变形大小、应变三个方面与模型试验结果进行对比分析,结果表明两者具有很好的一致性,同时证明了本文碰撞数值仿真方法的有效性。It is significant to study the dynamic response of stiffened panels subjected to lateral collision loading for further investigations of mechanical mechanism and promotion of structural crashworthiness design of ship collision. Based on experimental of series results of stiffened panels conducted recently, 5 typical models of the stiffened panels are simulated in the same case of the tests, and the dynamic response characteristics are obtained in various cases of stiffeners. At the same time, the simulated results are compared with the experimental data from the aspects of damage deformation mode, deformation amount and strain, and show a great agreement, which verify the validity of the simulated method employed in this paper.
