Abstract:
The performance of a badminton stroke is governed by a complex interplay between racket string properties, im pact force, launch angle, and aerodynamic effects. In this study, we present a numerical simulation framework to investigate the influence of string tension, impact force, and launch angle on shuttlecock exit speed, flight distance, and trajectory. Idealized elastic models are first introduced to establish theoretical upper bounds, followed by more realistic simulations incorporating aerodynamic drag and player-dependent efficiency. The results reveal that while increased string tension enhances shuttlecock exit speed in an idealized model, the effective performance exhibits a non-monotonic behavior when human factors are considered. Furthermore, aerodynamic drag significantly alters optimal launch angles and flight distances. These findings provide physical insight into racket-string optimization and practical implications for player performance and equipment design.
