ABSTRACT
Measurements of the coefficient of restitution (COR) for golf balls are presented using several different techniques and measures. The goal was to obtain a workable model for predicting relative velocities from driver-ball impacts, based on COR measurements. This information could provide a valuable tool for use in the research of new materials concepts for use in golf ball design. Several models were developed and are presented using two different COR measurement techniques, as well as using an unrestricted and a restricted approach with regards to ball types. Results show good correlation between ball velocities from a driver impact and COR data for the club head COR measurement technique. The correlation between ball velocities and COR data from the infinite mass COR technique was improved by restricting the model to solid ball types.
