概要

At the current stage, the terms used in describing the performance of a tennis racket are based on the feeling of an experienced tester or a player. However, the optimum racket depends on the physical and technical levels of each user. Accordingly, there are a number of unclear points regarding the relationship between the performance estimated by a player and the physical properties of a tennis racket. It is said that although the racket, which adopted the thermo plastics, has a high vibration damping and a soft feeling during impact it cannot be light weighted owing to the weak strength resulting in the inferior power. This paper has predicted the performance of the thermoplastic composite tennis racket comparing with the normal composite in terms of the power. It is based on the experimental identification of the racket dynamics and the approximate nonlinear impact analysis with a simple forehand swing model. The predicted results could explain the mechanism of difference in power between the rackets with different physical properties.
