| 目的 开发一套基于三维几何模型的船舶扶强材自动理想化系统。方法 针对船舶模型中扶强材截面形状、尺寸多变，分布密度大，进行结构规范计算时计算量大、计算条件复杂、人工计算难以涵盖全面的问题，考虑扶强材的截面变化、依附结构与相交关系，将船舶模型中的扶强材离散重组简化为单元梁，并以单元梁为基本单位进行船体梁结构相关强度校核参数的快速自动计算。结论 通过扶强材自动理想化系统，实现了对船舶扶强材间距等13项规范校核参数的快速自动计算，提高了船舶规范校核精度，缩短了船舶规范建模周期。 |

| The paper aims to develop an automatic idealization system for ship stiffeners based on a three-dimensional geometric model. In view of the variable shape and size of the stiffeners in the ship model, and the large distribution density, the large calculation of structural rules, the complex calculation conditions, and the difficulties for manual calculations to cover comprehensive problems, considering the cross-section, the attachment structures and the intersection relationships, the stiffeners were reconstructed into unit beams to calculate relevant strength parameters of hull girder structures and hull stiffener plate structures with unit beam as the basic unit quickly and automatically. Through the automatic idealization system of stiffeners, fast and automatic calculation of 13 standard verification parameters such as the distance between stiffeners is realized, improving the accuracy of ship specification verification and shortening the cycle of ship specification design. |
