船舶碰撞损伤危险区间界定研究

Definition of Dangerous Zone for Ship Collision Damage

以两艘10 000t级单舷侧结构散货船为研究对象,将被撞船划分为"船首球鼻首段""船中货舱段"和"船尾机舱段"三个区间段,基于有限元仿真技术和风险评估方法,综合考虑碰撞应力、结构损伤、能量变化,以及碰撞概率和后果,最终界定船舶碰撞最危险区间段,并提出减少碰撞损伤和损失的建议.结果表明,船尾机舱段为最危险碰撞区间段,驾驶员在碰撞不可避免时应避开此区间段.

Taking two 10000 DWT single-hull side structural bulk carriers as the research objects,the collision zones were divided into three sections:the bulb-bow section of bow,the cargo hold section of midship and the cabin section of stern.Based on the finite element simulation and the risk evaluation method,the most dangerous zone of the ship collision was defined by considering the collision force,structural damage,energy exchange,collision probability and collision consequence.In addition,the suggestions for reducing collision damage and loss were proposed.The results show that the cabin section of stern is the most dangerous collision zone and the crew should avoid the dangerous zone when the collision is inevitable.
