The invention discloses a rudder ball manufacturing method and a rudder ball, and relates to the technical field of ship and ocean engineering, and the method comprises the following steps: determining an initial molded line of the rudder ball; applying a first control curve and a second control curve to the initial molded line of the rudder ball; enabling the first control curve and the second control curve to control the shape change of the initial molded line of the rudder ball; introducing a supplementary line segment connected with the rudder ball initial molded line, wherein the supplementary line segment and the rudder ball initial molded line form a rudder ball molded line; and changing the rudder ball molded line to form a three-dimensional rudder ball curved surface. According tothe method, the first control curve and the second control curve are applied to the rudder ball initial molded line to control shape transformation of the rudder ball initial molded line, smooth transition between the rudder blade and the tail end of the rudder ball can be guaranteed, and the transformed rudder ball has continuity, attractiveness and good hydrodynamic performance; the shape of the curved surface of the rudder ball can be adjusted by adjusting the first control curve and the second control curve, the optimization process is simple, and good iterability is achieved.
本申请公开了一种舵球制作方法及舵球,涉及船舶与海洋工程相关技术领域,该方法包括以下步骤:确定舵球初始型线;对舵球初始型线施加第一控制曲线和第二控制曲线;第一控制曲线和第二控制曲线控制舵球初始型线的形状变化;引入与舵球初始型线连接的补充线段,补充线段和舵球初始型线构成舵球型线;变换舵球型线以形成三维舵球曲面。本申请中对舵球初始型线施加第一控制曲线和第二控制曲线,以控制舵球初始型线的形状变换,能够保证舵叶与舵球末端的光顺过渡,使得变换后的舵球具有连续性、美观性,及良好的水动力性能;调节第一控制曲线和第二控制曲线即可调节舵球曲面的形状,优化过程简单,且具有良好的可迭代性。
