摘　　要：船舶结构大部分是由节点连接在一起的,了解节点的受力特性及内力分布规律,可以指导改善节点设计,有利于整艘船舶。文章针对梁肘板节点,利用有限元对其强度和应力分布状况进行研究,讨论了肘板臂长、厚度及骨材端部间隙对应力计算结果的影响,从等强度和应力集中的角度进行分析,提出规范中该节点的合适尺寸建议。Ship structures are mainly joined with the structure details, it is very useful to find out the mechanics characteristics of structure details for improving the design of structure details. This paper studies the strength and the stress distribution of beam bracket by finite element method. The influence of stress results with the variation of bracket arm length, thickness and gap of beams is discussed. Suggestions for this structural detail is given for Rules.

关 键 词：梁肘板 船舶节点 应力分布 有限元
