Analysis of Impact Sound According to Changes of Golf Driver Face Thickness

Abstract

In this study, the characteristics of the impact sound according to the thickness change of the golf driver face were analyzed using dynamic analysis. A total of six cases with different thicknesses were selected based on the 3.2 mm face thickness of titanium material, and analysis conditions were set by referring to various experimental conditions. The acceleration data derived through Ansys motion solver was analyzed, and it was converted into sound pressure data using the RI equation to analyze the decibels and frequency values for each case generated at the time of swing. The results, As the driver face thickness increased, the frequency value increased, while the decibel decreased. Research model generated 2,700 Hz to 3,100 Hz and it was confirmed to be within the range of 2,500 Hz to 3,800 Hz. So this research method was analyzed to be appropriate.
