| 摘 要： | 提出采用细分曲面进行船体曲面造型,结合多边形及多面体的几何特性计算公式进行船舶静水力性能参数计算新方法。推导并整理出两套多边形及由三角单元围成的多面体的几何特性计算公式。根据文中方法对一组数学船型的部分静水力参数进行计算,并将计算结果与精确解进行比较,验证该方法的有效性。同时与传统的辛普生法、Maxsurf软件计算方法作了比较,说明所提出方法的有效性和通用性。

| Abstract: | Curved surface shaping of ship hull by subdivision surface was presented, a new calculation method for ship hydrostatic properties was put forward based on the formulas of geometry property. In the paper, two formulas were given to Calculate the geometry properties of polygon and polyhedron. The hydrostatic properties of designed mathematical ship models were calculated, and the numerical results were compared with the theoretical results and those by other methods, which validated the proposed method. |
