Abstract

A method for designing a golf club head by using a computer. A golf club head model in which the rear surface of a face part is provided with reinforcing ribs and a golf ball model to be analyzed by using a finite element method (FEM) are prepared. Conditions including the positions of the reinforcing ribs and the configurations thereof including the sectional areas and heights are adjusted to set the maximum value of the Mises stresses generated by the collision between the golf ball model and the golf club head model at any off-center positions of said front surface of said face part thereof to less than 1.3 times the maximum value of the Mises stress generated by the collision between the golf ball model and the golf club head model at the center of said front surface of said face part thereof.

Description

[0001] This nonprovisional application claims priority under 35 U.S.C. §119(a) on Patent Application No(s). 2005-202727 filed in Japan on Jul. 12, 2005, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention relates to a method of designing a golf club head by utilizing a computer. The present invention also relates to a golf club head. More particularly, the present invention relates to a method of efficiently designing a golf club head having a sufficient strength and excellent restitution characteristics. To do so, a golf ball model and a golf club head model both composed of a plurality of finite elements are used. Further reinforcing ribs are formed on the rear surface of the face part of the golf club head model. By changing conditions of the reinforcing ribs, ball-hitting simulation is executed to make stresses generated at any hitting positions of the face part uniform. [0004...
