ABSTRACT The substance of this study is to analyze the impact process between golf club head and golf ball by integrating the capability of the CAD software I-DEAS and the finite element analysis software LS-DYNA. The various golf club head can be created much easily by determined the dimension parameter in the variable-parameter characteristics of I-DEAS. The computational cost can be reduced by explicit central difference method of LS-DYNA. This study is to analyze the impact effect of varied thickness based on Taguchi method of experimentation and off-center hit in difference volume club head. After that, the hitting area, the sweet spot of club head and influencing factors of impact effect are discussed. It is expected that the findings of the study may provide engineers with some effective method to deal with golf club head design.
