摘　　要：加强结构以保证船体的结构强度为主,合理选择结构形式对于船舶安全航行至关重要。为此,采取奇异强度理论与ANSYS数值模拟方法比较分析了4种典型二维结构拐角处的应力分布及其奇异性,进而针对6种船用典型三维结构,分别在拉伸载荷、弯矩载荷及共同作用的工况下,分析并比较了结构拐角处不同方向的应力分布,并明确了有限元分析方法,希望为实际工程应用提供参考。To ensure the structural strength of the hull for the safe navigation, choosing a reasonable strengthening structure is essential. In this respect, taking the singular strength theory and numerical simulation with ANSYS to analyze the stress distribution and singularity of four kinds of typical two-dimensional structures on the corner. And then for six kinds of typical three-dimensional structure of marine, comparing the stress distribution in different di- rections at the corner of the structure under the conditions of tensile load, moment load and interaction respectively, also giving a better understanding of the finite element method. It is hoped that can be brought into real engineering.
