| 中文摘要: |
| 船舶发生碰撞多是在一些比较恶劣的海况下,事实上碰撞过程是碰撞作用和外部环境载荷作用的耦合。基于非线性有限元方法,建立考虑波浪载荷作用下船舶碰撞模型,对碰撞过程进行数值仿真模拟。对有无波浪存在下的碰撞结果进行对比,并分析波浪波高以及波浪入射角度对被撞船舷侧结构的影响。仿真结果表明,在一定情况下波浪载荷对碰撞过程有不利的影响, 因此在研究中应予以考虑。 |
| 英文摘要: |
| Ship collision often take place under the severe sea condition. In fact, collision process is contact force and external environment load coupling. Based on the non-linear finite element method and built ship collision model considered the effect of wave load, this paper simulates the colliding process numerically, compares the results of collision under condition with or without wave load and analyzes the influence on side structure by the wave heights and incident angle of the wave. The results of simulation indicate that wave load have negative effects on ship collision, therefore it should be considered in the study. |
