| 摘 要： | 船体板架是舰船中最主要的结构形式,研究在水下接触爆炸作用下的船体板架毁伤过程对于舰船的抗爆抗冲击设计具有重要意义。借助AUTODYN通用软件,建立船体板架水下接触爆炸数值模型,同时运用耦合欧拉—拉格朗日算法进行计算,并与试验最终失效模式进行对比,吻合良好。分析了水下接触爆炸作用下船体板架毁伤全过程,并对船体板架破口的形成和扩展进行了分析,探讨了加强筋的破坏模式,提出了板架结构中板和加强筋破坏模式的耦合效应。通过研究,揭示了水下接触爆炸作用下船体板架的毁伤特性。

| Abstract: | Plate frame is the main structure of ships.With the AUTODYN common software,numerical model of the plate frame by underwater contact explosion was established by the couple of the Largange and Euler code,and the simulation results agreed well with the experiment failure mode.Then,the whole fail ure process of the plate frame by underwater contact explosion was analyzed,and the formation and exten sion of the crevasse with failure mode of reinforcement was discussed.Besides,the failure mode coupling effect of the plate frame and reinforcing plate was proposed.The results demonstrate the damage character istics of the plate frame. |
