| Abstract/Contents: | "A large percentage of golf shots are putts, but there has been relatively little investigation of the interaction between the ball and the green surface in putting. Previous theoretical results predict that a ball rolling on a viscoelastic surface experiences a rolling friction force which varies with velocity. To determine surface viscoelastic properties, experimental drop tests of balls and wooden blocks on a green were carried out using an accelerometer and LVDT to simultaneously measure acceleration and position. Even from small drop heights (2cm) several bounces are observed, with contact duration increasing in successive bounces because of the increasing stiffness of the green surface with depth. Equilibrium penetration depth of 2.2mm and peak accelerations of about 50 g's were observed. Rolling trajectories of balls were measured using 60 Hz video cameras and the coefficient of rolling friction was determined using a parameter estimation procedure. Rolling friction was found to be nearly constant, changing by only about 10% during a single roll, but in the opposite direction to that predicted by the viscoelastic theory of Flom and Beuche (1959), implying that plastic deformation of the grass blades in the soft upper surface layer or their slip on the ball is important, rather than the viscoelastic parameters of the soil subsurface." |
