Abstract

The objective of this study was to grasp the relationship between golf club conditions and the rebound of a ball, and to investigate the factor of the relationship using a finite element (FE) analysis on a ball colliding with a simplified club. The clubs were constructed by holding simplified clubheads in a locking ring fitted onto a steel shaft. The clubheads were designed with reference to the mass, volume and position of centre of gravity of commercially available clubheads. FE models with linear elasticity of the clubs were constructed. The FE model of the ball consisted of 8-node solid elements, and the material model was expressed as a hyperelastic/viscoelastic model. Impact experiments were also conducted for comparison to confirm the accuracy of the FE models. The results of impact simulations closely matched the experimental results. The ball rebound was analysed using the constructed 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 of direction parallel to the axis of shaft which depended upon Young's modulus and the weight and position of the added mass.
