Abstract
During a golf swing, a bending and torsion occur on the shaft of a golf club, and it changes a head speed and a head angle etc. The behavior of such a golf club mainly originates in the input from a swing of a golfer. In recent years, many researches and development pay their attention to more upstream stage of the swing motion. Moreover, to understand the mechanism which connects a swing and a golf club behavior, many researches in consideration of the oscillation characteristic of the golf club and of a simulation by Multi Body Dynamics are being studied. This paper, which studies the highly accurate analysis technology in consideration of those all, shows the technology called Swing Simulation. It can predict a golf club behavior during a swing, formed by Multi Body Dynamics constructed with three-body golf club model with oscillation characteristic and by a three-dimensional displacement data reproducing swing characteristics. Compared a simulation result with actual golf club behavior, such as a position, a head speed and a bending, a simulation accuracy is confirmed.
