摘　　要：为了研究邮轮上建舷侧门窗角隅形状对结构强度影响,基于有限元细网格计算分析方法,对比3种新型角隅形状方案应力水平,在得到最优方案(方案3)后,借鉴贪心算法原则,进一步研究最优方案形状参数对角隅应力水平的影响。结果表明:方案3角隅形状对应应力水平最低,且方案3中椭圆弧半长轴a越大,角隅处最大合成应力越小;半短轴b根据角隅处主应力的方向进行调整也可降低角隅处应力水平。研究成果可为大型邮轮上建舷侧门窗开口角隅形状设计提供一定参考。In order to study the influence of the corner shape of the side door and window on the structural strength of the cruise ship,based on the finite element fine mesh calculation and analysis method,the stress levels of three new types of corner shape schemes are compared.After obtaining the optimal scheme(scheme 3),the principles of the greedy algorithm are referenced to further study the impact of the shape parameters of the optimal scheme on the stress level at the corners.The results show that scheme 3 has the lowest corresponding stress level at the corners,and in scheme 3,the larger the semi-major axis a of the elliptical arc,the smaller the maximum combined stress at the corner.The semi-minor axis b can also be adjusted according to the direction of the principal stress at the corner to reduce the stress level there.The research results can provide certain references for the design of corner shapes of side door and window openings on large cruise ships.
