摘　　要：基于有限元法采用MSC.Patran/Nastran对3 000t内河油船货舱段满载下的最危险受力状态进行强度计算,并结合CCS规范和指南分别从模型建立、载荷计算、应力分析等方面论述结构分析方法,结果表明该油船船体主要构件满足强度规范要求。Based on the finite element method, MSC. Patran/Nastran is used to calculate the strength of the most dangerous state for the 3 000 t oil tanker cargo hold structure with the full load conditions. And the structural analysis methods are discussed from the aspects of model establishment, load calculation and stress analysis combined with the CCS specifications and guidelines. After calculation and analysis, the results show that the ship structure strength meet the requirements of strength specifications.
