Study of Influences of Characteristics of Golf Club on Impact Phenomenon

In this study, the influences of the characteristics of golf dub, such as the rigidity of shaft and spring constant of head, are examined on the impact phenomenon such as the dynamic deformation of shaft and the release velocity of ball by the analysis on the ball-head hitting line. As the results of numerical analysis, it is seen that the optimum spring constant of head is as same as the one obtained by impedance matching condition even if the dynamic deformation of shaft is considered. It is also seen that the release velocity of ball isn't influenced by the dynamic characteristic of shaft when the impact phenomenon is only considered.
