基于规范设计的散货船货舱结构横向强度分析

Transverse Strength Analysis of Bulk Cargo Compartment Structure based on the Design Specification Method

中小型船舶在横浪作用下横摇会加剧。为保证船舶结构足够安全,就必须对现有规范设计的船舶进行横向强度校核。本文采用MSC.NASTRAN软件,对一散货船在满载和压载两种工况下的横向结构做强度应力分析比较,计算结果表明船体结构能满足横向强度许用要求,为今后散货船规范设计提供借鉴和技术参考。

Small and medium-sized ships＇rolling motion will become more severe under the effect of transverse wave. In order to ensure the safety of ship structure is enough, the existing specification design ship must do checking of transverse strength . Based the finite element method of MSC. NASTRAN, the bulk cargo compartment structure was analysed respectively under two cases （full load case and ballast case ）. The results show that the hull structure can satisfy the requirement. It provides important reference for future bulk carrier specification design.
