本设备使用一个以钟摆方式安装的钢球，以便摆动撞击一个高尔夫球杆的头部表面。高尔夫球杆的一端固定在设备底座上的一个垫块上，球杆头部自由安装，并且面对撞击球。撞击球从一个固定位置摆动，以撞击高尔夫球杆的头部，并且用一个示波器记录球与球杆头部表面撞击后球的加速度和运动，还计算球表面的速度随时间的变化。确定达到最大速度的时间。可以进行几次撞击，以得到多个计算的时间，然后根据下面的方程估算高尔夫球杆头部的相对柔韧性：B=t#-[c]-A・1/V#+[K]#-[m]也可以使用一个更简单的方法，使用一个单一的速度(进行一次或更多的撞击)。在这种情况下，高尔夫球杆头部的相对柔韧性根据下式估算：B＝t#-[c]。 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
