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