A25 ラケットとテニスボールの衝突解析(テニス)

抄録

Tennis is played by very wide people. So, various kinds of rackets are demanded. As a result, to develop various kinds of rackets in a short term has become necessary. However, the phenomenon of the impact between the racket and the ball is very complex, so the analysis is difficult. In this research, the impact between the racket and the ball was studied experimentally. The behaviors of the ball during the impact were analyzed using high speed images. According to the experimental result, the following conclusions can be obtained. There are three processes in the rotational speed of the ball during the impact. The rotational speed of the ball after the impact increased with increasing the displacement of the ball in the parallel direction to the surface of the strings. The rotational speed of the ball decreased with increasing the displacement of the slide of the ball.
