Distance and accuracy are required in golf swing. In order to hit a shot of maximum distance, swing linear velocity at impact phase must be maximum. Since dynamics of club and arm dominates the overall behavior of the swing, the dynamical mechanism of the arm and the club must be clarified for understanding the mechanism to produce the maximum velocity of the club. As a step toward understanding the mechanism, we investigated how non-muscular (e.g. centrifugal, Coriolis, and gravity) forces of the each link generates, absorbs, and transfers mechanical energy in order to produce the maximum velocity. This was accomplished using multi-body power analysis derived entirely from dynamical equations of a three-dimensional double pendulum with moving pivot model.
