METHOD OF ANALYZING PHYSICAL PROPERTY OF GOLF BALL AND METHOD OF MAKING FOR GOLF BALL

摘要

PROBLEM TO BE SOLVED: To provide a method of analyzing the physical properties of a golf ball using finite element method based on useful mesh division.;SOLUTION: An eighth model is obtained through the step A1 of imagining a microscopic cube; the step A2 of obtaining nodal points by dividing the microscopic cube using a mesh; the step A3 of obtaining new nodal points by projecting onto the spherical surface of a microscopic eighth sphere the nodal points contained within any of six planes of the microscopic cube that do not coincide with three planes of an eighth sphere;, the step A4 of dividing a space between the spherical surface of the microscopic eighth sphere and the spherical surface of the eighth sphere by use of the spherical surfaces of a plurality of intermediate eighth spheres whose centers are located at an original point; and the step A5 of repeating the operation of projecting the nodal points present on the inner spherical surface onto an outer, adjacent spherical surface, from the microscopic eighth sphere to the eighth sphere via the plurality of intermediate eighth spheres. The eighth model is expanded to obtain a finite-element golf ball model.;COPYRIGHT: (C)2002,JPO
