摘　　要：船舶碰撞通常导致船舱进水或变形、海洋环境污染以及人员伤亡等后果.为提高船舶舷侧的耐撞性,以某双壳油船舷侧为研究对象,设计一种齿型纵桁,并将其与传统舷侧结构相结合,形成一种新型舷侧结构.采用数值仿真软件建立舷侧模型,选取舷侧3个典型位置,对比新旧结构的吸能能力、碰撞力峰值和极限撞深.数值仿真结果表明:齿型纵桁舷侧结构具有较好的耐撞性.Ship collision is a common form of marine accidents,usually resulting in Cabin floods or deformation,marine pollution and casualties and other consequences. In order to improve the crashworthiness of ship broadside,we take a double hull oil tanker as the research object,design a tooth girder,and apply it to the traditional side structure. Using numerical simulation software ABAQUS,we establish a broadside model,select three typical broadside positions,and compare the energy absorption capacity,the impact force and limit hit depth of the new and the old structures. Simulation results show that the tooth stringer side structure has better crashworthiness.
