【摘要】 采用数值仿真的方法对船舶碰撞动力学过程进行仿真再现。系列仿真计算结果表明,传统的舷侧结构在耐撞性能方面存在很多缺陷,针对大型VLCC船舶设计帽形、菱形、半圆管形三种新型纵桁形式的双层舷侧结构模型,并从碰撞载荷、结构损伤变形、能量的吸收与转换等角度对此三种新型舷侧结构与传统舷侧结构的耐撞性能进行对比分析,结果表明半圆管纵桁形式的双层舷侧结构模型具有最好的耐撞性。更多还原

【Abstract】 The numerical method was employed to simulate the whole dynamic process of ship collision,and the results showed that the conventional side structure has many disadvantages against collision.Models of three kinds of new type side structures including hat-profile,diamond-profile and semicircle-profile were established for a VLCC,and the crashworthiness was compared between the new type models and the conventional model in the aspects of impact loading,damage deformation and energy absorption and transformation.The results indicated taht the semicircle-profile model has the best crashworthiness.更多还原
