<p>PROBLEM TO BE SOLVED: To improve the efficiency of a design of a golf club shaft by predicting a static physical property value such as the bending and twisting quantity of a shaft with high accuracy without producing a prototype for a shaft. SOLUTION: A golf club shaft made of a fiber-reinforced resin composed of a laminated body of fiber-reinforced pre-preg is set as a model for an analysis object, a modeled shaft is divided in the circumferential direction of the shaft, a laminated state of the fiber-reinforced pre-preg being data of a shaft configuration is inputted in each divided area, simulation is performed with a finite element analysis to predict a static physical property value such as the bending and twisting quantity, etc., of the shaft.</p> |
