Modelling the acoustics of a golf ball impacting a titanium plate

Abstract

Finite element techniques are often applied to the design and development of golf clubs. While distance and accuracy are the primary design characteristics, the acoustics of the ball/club impact play an important role in player perception. Previous work has applied finite element techniques to predict the sound of a golf ball/club impact. This research helps to lay the foundations for implementing finite element techniques into the process of developing golf clubs which produce a perceived 'desirable' sound upon impact. This study investigates the application of Ansys/LS-Dyna to predict the frequency response of a golf ball impacting three cylindrical titanium plates of varying thickness. A golf ball was fired against each plate at 41 m/s and the sound was recorded using a microphone. Fast Fourier transformations were applied to the sound recordings to obtain the frequency modes. A finite element model was developed for each plate and acoustic simulations for ball/plate impacts were run using the Rayleigh method. Averaged across all three plates, the mean frequencies obtained from the impact simulations for the first two modes were within 3% of those measured experimentally. Further research could work towards applying the techniques presented here to a golf ball/club impact. © 2014 The Authors. Published by Elsevier Ltd.
