We developed a device that could rotate a real golf ball up to 10000rpm in a wind tunnel. By using this device, we can measure aerodynamics forces with highly rotating golf ball under various spin parameters. Golf ball trajectory could be calculated by using this aerodynamics force. However, some undesirable circulated oscillations to measure the aerodynamic forces had occurred with the condition of highly rotating golf ball. Then some improvements had made to restrain these oscillations. As a result, less oscillation device had achieved in this study. The influence of the ball oscillation against aerodynamics force and trajectory calculation of golf ball was discussed.
