Abstract
A method (100) and system (20) for predicting a coefficient of restitution (COR) of a golf club (30) or golf club head (36) is disclosed herein. The system (20) and method (100) are able to predict the COR in a non-destructive manner for a particular golf ball and impact speed. The system (20) and method (100) utilize a vibration sensor (24) attached to the face (34) of a golf club (30). The vibration sensor (24) is excited with an excitation device (26), and data is transmitted to an analyzer (22). A mathematical model of the golf club (30) is created allowing for the coefficient of restitution to be predicted without destroying the golf club (30).
