基于LR-SDA的自卸式散货船强度分析

摘要

以某68 000 DWT自卸式散货船为研究对象,依据英国劳氏船级社(LR)的散货船结构设计评估程序,采用大型通用软件MSC.Patran/Nastran以及LR自主开发的ShipRight软件,对该船的船中区域结构强度进行评估,并提出若干加强建议.%This paper introduces the structural strength assessment of the mid-hold of a 68 000 DWT self-unloading bulk carrier based on LR rules.Further,according to the results of the analysis,some local reinforcement designs are put forward.MSC.Patran/Nastran and ShipRight of Lloyd's Register are used for the finite element calculation.
