Abstract

An explicit finite element (FE) model of a tennis ball impact on a freely suspended racket was produced in Ansys/LS-DYNA 10.0. The geometry fro the racket frame was reproduced in the FE model using a non-contact laser scanner. The model was validated against experimental data obtained in the fully automated International Federation Racket Power Machine. The room mean squared error between the model and experimental data was 1ms-1 for the rebound velocity of the ball for typical velocities of over 40ms-1. The method can be applied to different rackets and other sports equipment to determine rapidly the performance characteristics of new designs.
