In this paper, the effects of the natural frequencies of ball and head are investigated on the restitution performance in order to develop a superior club head with high restitution performance. Firstly, the coefficient of restitution is calculated by using the lumped mass models of ball and head. As a result, the coefficient of restitution increases when the natural frequencies of ball and head where the contact part is fixed or free, coincide with each other. And the coefficient of restitution is bigger when the natural frequencies of ball and head where the contact part is fixed, coincide with each other than when the natural frequencies of ball and head where the contact part is free, coincide with each other. Next, the ball and head are modeled by three-dimensional models and the release velocity of ball after impact is calculated. As a result, the maximum release velocity of ball can be obtained when the natural frequencies of ball and head where the contact part is fixed, coincide with each other.
