Classification of differences in deformation behavior of shafts with different kick points

Abstract

For golfers, using a shaft that suits them gives good results to the shot content such as flight distance and hitting direction. On the other hand, if they use a shaft doesn’t suite them, it is necessary to adjust the movement during the swing due to the difference in sensibility. Therefore, we have developed a system that proposes the suitable shaft for golfers. The goal of the system is to propose a shaft that not only improves the trajectory but also the feeling. For that goal, in this research, we investigated how changes in shaft characteristics affect sensibility. First, we measured the swing using shafts with different kick points and calculated the deformation behavior of the shaft. Second, we classified golf swings and clarified the difference in deformation behavior for each pattern. Finally, we investigated the relationship between shaft deformation behavior and swing pattern, and considered the effect on sensitivity, so we report the details.
