Approximate 1.00 inches of ground apart from D3.When according to United States Golf Association（USGA）When CT tests are measured with μ s, structural connection
50th, 52 this positioning and optimizing standardization ball speed and characteristic time（CT）Relation.
Standardization ball speed to golf with any given glof club head（Include the golf of the present invention
Head 10）The quality and loft and specific golf of glof club head are eliminated in the test of speed during shock
Construction variable influence；In other words, the comparison of its same benchmark for allowing glof club head performance.Following step can be used
The rapid ball speed that standardization is determined for glof club head, these steps are also summarized in the flowchart of fig. 9.
First, there is provided the quality with approximate 190 grams, approximate 4 inches of diameter D as shown in Figures 10 and 114, it is approximate
0.100-0.150 inches of minimum thickness T1With approximate 0.200-0.400 inches maximum gauge T2Titanium 6-4 calibration plates 90, and
And to the center 92 of the approximate 109 mph test golf beating calibration plates moved（Step 100）.Measure the return speed of ball
DegreeV br （Step 110）.Then, impacted again near with the center 34 of the impact surface section 30 of evaluated glof club head 10
The identical test golf advanced like 109 mph（Step 120）, and measure the rebound velocity of test golfV cr
（Step 130）.Then, the quality of measurement and data boardm p , golf qualitym b , glof club head 10 qualitym c , survey
The speed of ball is tested on the head obtained（109 mph targets）V cin , the speed of board test ball that measures（109 mph targets）V bin , survey
The head test ball return speed obtainedV cr With the board test ball return speed measuredV br （Step 140）.Finally, using such as the following
The ball speed of formula normalized（V ballnorm ）（Step 150）：
In the equation,V inh For 100 andm h For 200.
The glof club head 10 of the present invention hasV ballnorm >=0.0356x+140.82, and more preferablyV ballnorm
≥0.0356x+141.19.The positioning of structural connection 50,52 allows glof club head 10 to meet the equation；Such as institute in Figure 12
