摘　　要：本文以某沥青船为研究对象,依据中国船级社《钢制海船入级规范》(2021)的相关要求,对该船的总纵强度进行计算。计算工况选取满载出港、满载到港、压载出港、压载到港、半载出港和半载到港六种情况,运用大型有限元软件MSC Patran/Nastran,对该船进行基于温度场效应的总纵强度分析。计算结果表明,该沥青船结构强度满足规范要求。Taking a certain asphalt ship as the research object,this paper calculates the longitudinal strength of the ship according to the relevant requirements of China Classification Society's"Rules for Classification of Sea-going Steel Ships"(2021).The calculation conditions select six situations,namely full load departure,full load arrival,ballast departure,ballast arrival,half-load departure and half-load arrival,and the large-scale finite element software MSC Patran/Nastran is used to analyze the longitudinal strength of the ship based on the temperature field effect.The calculation results show that the structural strength of the asphalt ship meets the requirements of the specification.
