摘　　要：以15.9万吨级的满载双壳油船为研究对象,对以往研究经常忽略的被撞船不同货油舱被撞时对碰撞性能带来的影响进行分析。利用有限元软件ANSYS/LS-DYNA,分别对该船处于静止状态下被撞时的碰撞损伤机理和耐撞性能进行分析研究。通过对碰撞过程中产生的碰撞力、结构变形、结构吸能等进行计算、比较、分析,阐述被撞船不同货油舱被撞对结构损伤机理及碰撞性能的影响。研究结果表明,撞击不同货油舱对被撞船的碰撞性能的影响是不一致的。The effect of collision on the double-sided structure of 159,000 of oil tanker at full load condition is studied. The nonlinear finite element software, ANSYS/LS-DYNA, is used to investigate the collision damage mechanism and crashwor- thiness of this tanker when it is hit at its different cargo holds while the tanker has no speed. The collision force, deforma- tion and energy absorbing are computed, and the results are compared. The comparison indicates that colliding different cargo hold will cause different collision effect, which is the fact sometimes wrongly ignored.
