摘　　要：为保证船体结构安全性,以一艘耙吸式挖泥船为研究对象,利用水动力计算软件预报6种典型装载工况下的波浪弯矩。利用有限元软件分析11种工况下泥舱区域舱段总强度。计算结果表明,波浪弯矩对总强度计算结果的影响极大,本船在波浪作用下的结构强度满足规范要求。本文的计算方法对超尺度比挖泥船波浪载荷预报和强度评估有较大的参考价值。To ensure the structural safety of the hull,this study focuses on a rake suction dredger as the research subject.Hydrodynamic calculation software was used to predict wave bending moment under six typical loading conditions.Additionally,finite element software was utilized to analyze the overall strength of the mud compartment section under eleven conditions.The results indicate that wave bending moment significantly influence the overall strength calculations,and the structural strength of the vessel under wave action complies with regulatory standards.The calculation method presented in this paper provides valuable reference for wave load forecasting and strength assessment of ultra-large-scale dredgers.
