A model that calculates the deflections of a golf shaft during the swing was developed. Applying static deflection to a shaft which is flexible and has varying bending stiffness, a differential equation for moment and curvature which characterize its behavior over the duration of the swing were generated. Incorporated into concentrated moment are moment of forces acting at the tip and grip end of the shaft. These loads were calculated using a inverse dynamics analysis of the motion of the golf club during the swing. A motion capture system was utilized to collect the necessary data. Solutions to the equations for the shaft deflection were calculated numerically. The results are presented as deflections along the shaft at each time. Bending deflections are determined in two-dimensional direction.
