摘要
Classic Spar平台由于其单立柱式的几何特性,会产生较大的涡激力,而平台柱体外围的螺旋板能有效地减少涡旋,增加平台结构强度。本文应用三维分布源法求解边界积分方程,计算并比较了Classic Spar平台在四种不同水深时的水动力特性,分析了螺旋板的螺距和数量对平台水动力特性的影响。
Due to geometrical characteristics of Classic Spar,a large vortex force is generated.The spiral strakes are attached to the platform to reduce the vortex and to strengthen the structure.Three-dimensional distributed source method is used to solve boundary integral equations based on linear wave theory.A Classic Spar platform is selected to calculate its hydrodynamic forces in different water depth;The pitch and number of strakes were changed to understand their effects and influences to the hydrodynamic forces of the spar structure.
