The analysis of vibration of the arm and the racket is important to understand the performance of the racket and preventation of sports diseases when people play tennis. This paper discusses about interaction among a ball, a racket, and an arm at the impact. The ball, the racket, and the arm are modeled by masses, a flexible beam, and a rigid link, 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 presented. Finally, the parameter study is performed, and we show the effectiveness of the used parameter.
