The objective of this study was to construct a finite element model for simulating the mechanical behavior of a golf club and ball from swing to impact, and to evaluate club performances using the constructed model. An experiment using a golf robot was conducted to obtain the motion of the shaft grip, and the behavior of the club and ball. The swing model was developed by inputting the positional coordinate data of the grip, which was obtained from an experiment, into the grip model. The simulation results generally matched the experimental results. The ball launch behavior was analyzed using the model with different ball impact points. The ball launch velocity at impact points situated on the toe and sole side, rather than the sweet spot (SS), tended not to decrease as much from the SS impact. It was estimated that the trend was attributed to the distribution of the impact velocity of the clubhead, which tended to increase towards the toe and sole, from the heel and crown on the face.

本研究的目的是构建一个有限元模型，用于模拟高尔夫球杆和球从挥杆到撞击的力学行为，并使用构建的模型来评估球杆性能。使用高尔夫机器人进行实验，以获得杆柄的运动，以及球杆和球的行为。通过将从实验中获得的握把的位置坐标数据输入到握把模型中来开发挥杆模型。仿真结果与实验结果基本吻合。利用该模型分析了不同击球点的击球行为。在位于脚趾和鞋底侧的冲击点处的球发射速度，而不是甜蜜点（SS），倾向于不从SS冲击降低那么多。据估计，这一趋势归因于杆头冲击速度的分布，该速度从杆面的跟部和冠部向趾部和底部增加。
