Construction of a finite element model for a golf ball colliding with a club during a swing and an evaluation of a golf club performance

利用建立的有限元模型，通过改变杆件的杨氏模数和附加质量对高尔夫球的回弹进行了分析。回弹速度对回弹速度的影响较小，回弹角和自转速度受冲击力的影响，而冲击力取决于杨氏模数和附加质量的重量和位置。此外，还建立了一个有限元模型，该模型可以模拟竖井在二维摆动和冲击过程中的行为。然后，通过将碰撞行为的结果可视化为杆头面部的颜色图，提出了一种评价高尔夫球杆性能的方法。

The golf ball rebound was analysed using the constructed finite element (FE) models by varying Young's modulus of the shaft and an added mass attached to the shaft. The effect for the rebound velocity tended to be small, and the rebound angle and spin rate were affected by the impact force which depended upon Young's modulus and the weight and position of the added mass. Also, an FE model, which can simulate the behaviour of a shaft during a 2D swing and that of impact, was constructed. Then, an evaluation method for golf club performance was developed by visualizing the results of impact behaviors as a color map on the clubhead face.
