A29 ゴルフシャフトの特性評価に関する研究(ゴルフ1)

抄録

This paper considers the evaluation of jerk to design the shaft of a golf club. The jerk, the derivative of acceleration, is more sensitive and useful value. We think that the reduction of jerk means good feeling and reduction of power-loss during golf swing. The result of experiments shows that the jerk is available as a dynamic characteristic of golf club. The experiments were done with two golf clubs that the static characteristic is almost same, but the shaft has only difference fiber-allocation. We couldn't find the golf clubs' difference through the impulse hammering experiment of frequency response function, but we could find a little bit different behavior through the step excitation jerk frequency transfer function.
