Failure Investigation of Badminton Racket using Modal Analysis

From its humble beginnings in wood to its current slim geometry in high quality light weight carbon fiber composites, improvements in the badminton racket have largely been due to material advancements. The link between design and performance remains relatively poorly understood. Current rackets are designed heuristically, based on experience of the manufacturer and the player. The objective of this research is to add a scientific perspective to the design of badminton rackets, by studying the underlying physics of the game. The design of a badminton racket requires an understanding of the player, the racket, and how they interact in generating a stroke. The dynamics of the stroke can be used to assess their performance. Performance can be characterized in terms of power and control, which can respectively be quantified by the shuttlecock speed and the consistency of the stroke. Since the stroke involves both rigid-body and flexible-body dynamics of the racket it can be characterized by several stroke parameters such as racket head speed at impact from the rigid-body motion, and elastic deflection and elastic velocity at impact from the deformation behavior. This study based of the finite element method, a computer simulation method, to analysis the dynamic property of racket and string. Three-dimensional model was created Creo according to the geometry of a Yonex made graphite Badminton racket. Using ANSYS is done to calculate the modal frequency and shape; the results are to be obtained for determination of the failure in the badminton racket frame.
