In order to hit golf balls correctly, golfers are particularly concerned with the characteristics of their drivers. Therefore, golf clubs are designed to satisfy golfers' demands. However, the United States Golf Association has placed restrictions not only on the volume of the club head, but also on the coefficient of the golf club under the spring effect rule. It is therefore difficult to differentiate these specifications. Golf club developers use a variety of methods to customize clubs to individual golfer. One such technique is "database fitting," established by Sumitomo Rubber Industries, Ltd. (SRI). In the future, golf club developers would like to provide shafts customized to fit each individual golfer. In order to do so, it is necessary to predict shaft movement during a golf swing via simulation. Previous studies simulating shaft movement during a golf swing demonstrate shaft movement using a finite element method (FEM) model. A head was attached to a FEM model of the shaft as a simplified ridig model. Moreover to take the golfer's grip into consideration, we modelled the grip using potential grip energy during the swing. Using this simulation model, we simulated shaft movement while taking into account the golfer's swing. And resolving inertia force into its component elements, we simulated shaft movement. The objectives of this study are to verify the influence of the component of inertia force on shaft movement while taking into account the golfer's swing.
