Abstract: | Backspin rate and friction coefficients have been studied for a range of commercially available wedges and multi-piece golf
balls using a mechanical golfer and a modified pin-on-disc tester. Analysis of shot characteristics for wedges with three
different surface roughness values and two golf ball types (two-piece ionomer covered and three-piece polyurethane covered)
was carried out using the mechanical golfer, whilst pin-on-disc testing was performed to determine the friction coefficient
between the different golf ball covers (with a range of hardness values) and steel discs with a range of surface roughness
values seen for different wedges. It was found that the polyurethane covered balls (lower hardness) showed greater backspin
than the ionomer covered balls (higher hardness), and showed higher friction values during the pin-ondisc testing.
During the mechanical golfer tests, however, it was observed that the ionomer covered balls showed an increase in friction
coefficient for increasing surface roughness, although the effect of differences in cover material types was greater than
that of surface roughness variation for the same cover material within the range of commercially available wedge face surface
roughnesses. |
