THE EFFECTS OF GOLF SHAFT AND CLUBHEAD ON THE VELOCITY OF CLUB-HEAD AND BALL
Keywords: shaft bending stiffness, club head, golf
AbstractThe purpose of this study was to investigate 1) the influence of the bending stiffness of the golf shaft on the velocity of the club-head and the ball, and 2) the influence of different club-heads on the velocity of the club-head and the ball. Four different drivers made up of two different shaft stiffness (R-stiff, L-flexible) and club head (Titanium, Graphite) were used in the experiments. The results showed that the shaft stiffness L resulted in slower before-impact club head velocity than the shaft stiffness R, whereas the shaft stiffness L resulted in higher maximum ball velocity than shaft stiffness R. But the result in the statistics showed no significant club-head material effect on either clubhead velocity or the ball velocity. And there was no significant shaft stiffness effect on either club-head velocity or the ball velocity.
