摘　　要：利用有限元模型,分析T型材的制图标示方法和ANSYS软件型材剖面库中的定义方法,通过计算对比传统和精准方法下结构的抗弯能力,给出船用球扁钢的关键几何位置坐标,由ANSYS软件中得出的球扁钢主要截面属性与国家最新标准(GB/T 9945—2012)一致,实现了球扁钢在有限元模型中的精准表达。Relying on the FE model,the comparison was made between the graphical display method of the T-profiles and the definition method in the ANSYS software profile section library,and the calculation of the bending stiffness of the structure was made under the traditional and accurate methods.The key geometric position coordinates of the marine bulb profile were given.The main section properties of the bulb profile obtained in the ANSYS were consistent with the latest national standard(GB/T 9945-2012),which realized the accurate expression of the bulb profile in the finite element model.
