Abstract
The analysis of vibration of an arm and a tennis racket is important to understand the performance of rackets and the preventation of sports diseases when people play tennis. This paper discusses about the interaction among a ball, a racket, and an arm at the impact. The ball, the racket, and the arm are modeled by masses, flexible beams, and rigid links, respectively, and they are connected by springs and dampers. By coupling the dynamics of the ball, the racket, and the arm, the coupled equation of motion is derived. Finally, the parameter study is performed, and we show the results of experiments for parameter identification.
