Portable Apparatus for Measuring the Flexibility of a Golf Club Head

摘要

The apparatus employs a steel impact ball (55) which is mounted in a pendulum manner to swing against the face (16) of a golf club head (15). The golf club (14) is secured at one end to a spacer block (17) on the base (10) of the apparatus and the head (15) of the club is freely mounted in facing relation to the impact ball (55). The ball (55) is pivoted from a fixed position to impact against the head (15) of the golf club (14) and an oscilloscope is used to record the acceleration and movement of the ball after impact of the ball on the club face and also calculates a velocity history of the face of the ball. The time at which the calculated velocity is at a maximum is determined. Several impacts are made to obtain a number of calculated times and the flexibility of the golf club head is estimated in accordance with the results obtained
