EVALUATION METHOD OF GOLF CLUB, AND GOLF CLUB

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method of golf club, which can precisely show the rigidity of a shaft and the flying height of a hit ball, and a golf club which is evaluated by the method. SOLUTION: The frequency of a club shaft (1) per unit time is measured by vibrating the tip end part (102) in a condition in which the rear end part (101) is fixed. On the other hand, the frequency per unit time is measured by vibrating the rear end part (101) in a condition the tip end (102) is fixed. The rigidity of the club shaft (1) is evaluated based on the sum of both of the frequencies. The flying height of a ball hit by the club is evaluated based on the ratio of both of the frequencies.
