摘要
讨论船体薄壁梁剖面特性计算的4种主要方式,并以一个“标准”的船体剖面对采用各种计算方式得到的剖面特性参数的结果进行比较和分析,说明在大开口船舶弯扭组合强度计算分析中,采用等效板厚的方式引起的误差不大。
Four methods of section modeling in the calculation of the section property parameters for the thin-walled hull beam are introduced. Numerical results of the section property parameters obtained by using these methods for a standard ship section are analyzed, it shows that the traditional equivalent method of simplifying the areas of the longitudinal to the thickness of the plating is applicable to the bending-torsional strength assessment for the ships with large-deck-opening.
