DEVICE FOR EVALUATING IMPACT RESILIENCE CHARACTERISTIC OF GOLF CLUB HEAD

摘要

PROBLEM TO BE SOLVED: To provide a golf club head impact resilience characteristic evaluating device which obtains the restitution coefficient of a golf head without disassembling the golf club, and also easily obtains the restitution resilience characteristic in a short period of time by visiting a desired place.

SOLUTION: The golf club impact resilience characteristic evaluating device 10 includes: an analog input/output card 20 for fetching a response signal from a shot surface F which is generated by oscillating the shot surface F of the golf club head H with an impact; a frequency analyzing unit 22a for obtaining a first resonance frequency f on the shot surface F from the response signal; a restitution coefficient calculating unit 22b for obtaining the restitution coefficient e when a golf ball is shot against the shot surface F from the first resonance frequency f; and a display 22d for displaying the evaluation result of the golf club which is evaluated through the use of the calculated restitution coefficient e. The respective units are comprised in a mobile computer 22.
