Vibrational Characterization of Golf Clubs

For this experimentation project, I studied the vibrational response of two distinct golf clubs to find their natural frequencies and pinpoint their "sweet spots". Using a roving hammer test and a Data Acquisition (DAQ) system, I generated Frequency Response Functions (FRFs) to analyze how impacts at various points along the head and shaft translated into vibrations felt at the handle. By identifying the impact locations that produced the lowest magnitude of vibration at the first two bending modes, I was able to experimentally verify the optimal sweet spot for both an Iron-9 and a Driver. This analysis provided a practical foundation for understanding energy transfer efficiency, helping to determine how structural design can reduce reaction forces in a golfer's hands
