Badminton smashing point position and smashing move relational mechanical model research

Lin Li

Badminton is backbone fitness event in national fitness industry, the paper carries out detailed analysis of badminton smashing technique, and analyzes from the perspectives of mechanical and geometrical analysis so on. By mechanical analysis, it gets that when athlete makes smashing move, athlete takes-off and arrives at top point, he should keep body stable and reduce rotational angular speed, raise two legs and let gravity center to be far away from rotational axis. Establish stable base between racket and ball, and then construct geometric model, it gets when athlete smashes, they should try to stretch arms to the right ahead and keep vertical to hitting point, athleteÂ’s take-off height gets higher, and probability that all crosses net would be bigger, ball located hitting points are different and presented trajectory and landing points after netting are also different
