Abstract
A system for measuring rigidity characteristics that measures a CT value of a golf club head based on an acceleration occurring in an impactor when the impactor is caused to strike the golf club head. Correlation data is calculated by measuring a representative CT value of the golf club head, which is calculated based on CT values measured multiple times by changing the impact velocity of the impactor, and a test velocity CT value, which is a CT value when the impact velocity is set to a predetermined test velocity, for each of a plurality of the golf club heads of an identical model. A rigidity characteristic value measuring device measures the test velocity CT value for another golf club head of the model. A computer estimates the representative CT value of the other golf club head based on the test velocity CT value and the correlation data.
