ゴルフクラブの最適設計に関する研究

This paper deals with the optimum design of a golf club by tuning the shaft stiffness. First, an equation of motion is derived by the finite element method considering kinematic motion and vibration of the club. Then real swing data, that is, angular velocity and acceleration of a golf swing, are measured using a high-speed video camera and digital image processing. Applying these data to the above equation, the following results are obtained. It is found that in the process of optimizing, the design of the club head and shaft can be separated. Optimum flexibility is generally determined in proportion to the level of ability: optimum club shafts for beginners should be more flexible than those of more advanced players.
