In this study, the shape optimization of a golf club head is investigated. The shape optimization of a club head for maximizing the release velocity of the ball is treated. In general, for a shape optimization problem, it is necessary to derive the design sensitivity that expresses the relation between the variation of an objective function and the variation of the design variables. However, it cannot be derived analytically in impact problem due to the use of explicit method for impact simulation. In this case, numerical techniques, such as the finite difference method and the basis vector method can be used. We try to use the basis vector method for shape optimization. The basis vector method is applied to the optimal design of thickness distribution of a club head. We present an approach to create the basis vectors using eigenmodes. The release velocity of the ball is chosen as the objective function in the optimization process. A numerical example shows that this approach is effective to the optimal design of golf club head.
