• 論文の詳細を見る

• This paper has investigated the physical properties of a racket and has derived the contact forces, contact time, coefficient of restitution, and deformations during impact between a ball and racket. Furthermore, it has predicted the power or post- impact ball velocity with a forehand groundstroke. It is based on the experimental identification of the dynamics of racket-arm system and the approximate nonlinear impact analysis with a simple forehand stroke swing model. The predicted results could explain the mechanism of impact between a ball and a racket with different physical properties. It enables us to predict the various factors associated with impact and performance of the various racket.
