摘　　要：采用理论分析和数值模拟计算相结合的方法对某油船结构变形进行分析。通过建立舱段有限元模型,计算舱段的结构变形;借助三维软件Catia模拟生成和计算液舱容积,较精确地分析液舱在静压力下结构变形的大小及导致液舱容积的变化量,并对液舱容量修正提出相关建议。This paper analyzes the structure deformation of an oil tanker using theoretical analysis and numeric simulant calculation. First create the tank＇s FEA model and calculate the structure deformation, then use Carla to simulate and calculate the volume of liquid tank. At last compare the deformation and volume variation to make clear its influence to the volume of the tank and give some suggestions in studying the volume correction for reference.
