Golfers expect to hit a golf ball correctly by their golf clubs which concern driver. However, not only volume of head of the golf club but also coefficient of the golf club was restricted by the effect rule of the spring of the United States golf society. Therefore, it is hard to differentiate clubs spec of golf clubs. Then, the implementers of golf club increase these lineups of shaft and they provide the club fits for an individual. As for one of techniques, "Database fitting" was established by SRI. In the future, the implementers would like to provide custom-made shaft for each golfer. For achieving this purpose, it is necessary to replicate moving of shaft in swinging by simulation. There is a number of same generic simulation software, but it is hard to change shaft parameter. Improving these issues, we developed software which is capable of changing a shaft parameter more easily. In the past, we made swing simulation software as a first step. However this simulation software needs a lot of simulation time because simulation model have a lot of degrees of freedom. And so we employed mode synthetics method to reduce degrees of freedom which replicate golfers swing. In this report we calculated inertia force in golf Swing as double pendulum model. Using this inertia force, we simulate shaft dynamics in golf swing by FEM model of a club. Moreover we made grip model that replicates a golfer grip and analyzed using this model.
