补给作业船舷侧碰撞损伤环境研究

基于横向补给作业中各个阶段可能出现的舷侧碰撞模式所确定的两船碰撞发生时的夹角和补给作业船受撞位置,进行横向补给作业船舷侧碰撞损伤仿真研究。分析了补给作业船的吸能特性和碰撞过程中两船的运动状态,获得了碰撞力、能量吸收和损伤变形的时序结果。该文的研究可对于开展补给作业船舷侧碰撞结构损伤评估、舷侧抗撞结构的优化设计提供指导。

Research of store ship broadside collision damaged environment

Based on broadside collision mode, the angle of two ships while collision happening and impact-ed position of store ship in each stage is analyzed, and the damage behavior of a store ship broadside in collision is studied through numerical simulation by explicit non-linear finite element method. The time his-tory of collision force, energy absorption and structural deformation during collision are described. The damage mode and the resistant effects of the side structure and movement of the both encountered ships are analyzed and discussed. Some general instructive conclusions on behavior of store ship broadside colli-sion are obtained. The research work of this paper provides a guide for evaluation of side structural damage of store ship and optimization design of side structure.
