Currently, golf club design has been widespread. No matter the appearance changed, designed for center of gravity, material application, etc, they are all pursuing better efficiency of hitting. However, there will be no optimal design with emphasize on one of them. Thanks to the parameter design of golf head with simulating and analyzing golf ball trajectory, and modifying M.O.I., center of gravity, etc, the optimal performance of club head can be achieved. In this thesis, golf club models were set up by SolidWorks. The weight of club head model was decided by different class of users, and each class of club head had four types of hitting face structures individually. Then, their impact effect was simulated by LS-Dyna solver system. In this thesis, the hitting effect for different types hitting face was analyzing by including professional Male, Female, amateur Male, and Female four different tyes of users. Then the influences on ball linear velocity, the angular velocity and the trajectory were verified. The Men¡¦s PGA Tour suitable club is reticulate face. The Ladies¡¦ LPGA Tour suitable club face is uniform slab. The Typical Men suitable club face is concentric circle. The Typical Lady suitable club faces are concentric circle and reticulate face.
