主要研究不同主尺度和载货类型的运输船舶尾部结构设计的特点。针对近年来出现的轻型尾部结构分别进行整体挠度分析和模态分析，比较它与传统设计方式之间的差别；同时也针对尾部结构整体模态估算公式中有效剪切面积的计算方法进行探讨，在计入其影响后与有限元法模态分析的结果进行比较，并指出尾部结构轻型设计应当注意的技术要点。

This paper mainly studies the design characteristics of the stern structure for transportation vessels with different main dimensions and different freight types. It separately carries out the overall displacement analysis and mode analysis based on the recent lightweight stern structures, and compares with those of conventional design. At the same time, it discusses the calculation method of the effective shear areas in the overall mode estimation equation for the stern structures, and compares with the FEM mode analysis results by taking into account with their influences. At last, it gives the key techniques of the lightweight design for the stern structures.
