Analysis of coupled vibration of the arm, the tennis racket and the ball is important to understand the performance of the racket and to prevent sports diseases when people play tennis. The human system is modeled as musculo-skeletal model taking activity level into account, and the ball and the racket are modeled by masses, rigid links, respectively, which are connected by springs and dampers. By coupling the dynamics of the ball, the racket, and the human system, the coupled equation of motion is derived. Inverse-dynamics is employed and the torque is derived from the swing behavior. Furthermore, the neural network system is introduced to obtain the value of the muscular activity level. Finally employing the experimental swing data, we show dynamic interaction among the racket, the ball and the human system.
