| Research Abstract |
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.
