A31 ゴルフ・スイングにおけるパラメトリック加速 : ヘッド速度を増す力学の知恵(ゴルフ2)

抄録

The inward pull motion at the impact stage of the golf swing, commonly observed with expert players, is investigated in this paper. It is shown that the acceleration occurred by the mutual action of the two governing factors of the system, the centripetal force and the pull velocity. The phenomenon is to be called the parametric acceleration, following the parametric excitation of vibration problems that are governed by the similar equation. Based on the fact, a swing model consists of two links and one linear actuator is constructed on the Working Model Simulator. The result simulates accurately the swing of the expert professional golfer.
