82000dwt散货船结构强度有限元分析

为优化升级主流船型,对82000dwt散货船作了船体结构强度的有限元分析。首先根据2005年美国船级社规范,评估母型船的结构强度。其次根据散货船共同结构规范2008版及2009版,对开发的新船型进行了货舱结构的整体有限元分析和疲劳敏感区域精细网格有限元分析。计算结果表明,母型船的结构强度满足旧的规范要求,新船型的结构需要进行加强,新规范的修订有利于船舶结构设计的优化。

Finite Element Analysis of Structure Strength of an 82000dwt Bulk Carrier

Optimization and upgrading of ship types is one of the goals of adjustment and revitalization of China's shipbuilding industry.SDARI carried out the optimization and analysis of an 82000dwt bulk carrier.In this paper,the finite element analysis on ship structure strength of this vessel type is illustrated.Based on ABS rule 2005,the direct strength of the parent vessel is assessed;then the FE analysis of cargo hold structures and fatigue sensitive areas of the new developed vessel with very fine meshes is ca...
