| 摘 要： | 依据缓冲球艏设计要求,提出棱柱型艏柱设计方案,运用有限元分析软件LS-DYNA对采用传统艏柱与棱柱型艏柱结构的12 000 t油船进行船艏碰撞的仿真分析,发现棱柱型艏柱结构比传统艏柱结构球艏更易被压溃.

| Abstract: | According to design requirements of buffer bulbous bow,a design pattern of prismatic column stem structure was proposed.LS-Dyna was used to simulate ship collision process respectively for the ship with traditional stem and prismatic column bulbous bow stem of 12 000 t tanker.The simulation results showed that the prismatic stem structure of bulbous bow is easier to be crushed than the traditional stem structure. |
