The effects of the inertia property of a club head to the restitution property of golf balls were investigated. The three-dimensional inertia properties of a golf club head were expressed by using the inertia ellipsoid. The inertia ellipsoid was cut in the plane which was parallel to the club face and passed through the center of gravity. The correlation between the cut ellipsoid and the restitution property was shown. It became possible by using the cut ellipsoid to express the restitution property on the golf club face. The restitution property was predicted by using the collision model of the rigid bodies. Furthermore, it became possible to prescribe the area of the high restitution on the golf club face from the inertia property of golf club head, its mass and the mass of the golf ball. With the technique used in this research, it is possible to predict the direction in which a high restitution area spreads out in the restitution property specially at the design. And a high restitution area can be predicted on the basis of three measurements of the inertia moment. Furthermore, rigid body collision simulation Twas examined. The simulation is consistent with the result of the experiment. By using this simulation it is possible to do more suitable design of the golf club head.
