THE DYNAMICS OF GOLF CLUBS USING GENERIC FINITE ELEMENT MODELS

摘要

This paper compares the results of the dynamic modelling of a typical golf club and measurements made on the same club. The shaft was modelled using beam elements and the head was represented as a rigid body. The natural frequencies of the club were measured and compared to those predicted from the analytical model. The flexibility properties of the shaft were modelled using the generic parameter approach. These parameters and the inertia properties of the head were estimated from the measured data to produce an improved analytical model. Subset selection was employed to determine which parameters to update.
