Performance prediction of the badminton racket

(Static simulation of strings' deformation)

Abstract

Badminton racket is composed of string bed, frame, shaft and grip handle. A shuttlecock contacts directly with the strings where their deformation would affect the initial condition of the hitted shuttlecock. The final goal of this research will be to predict the performance of badminton racket by quantifying the influence of mechanical properties of the racket parts on the launch condition of the hitted shuttle. As the first step of the research, the purpose of this study was to propose a simulation method that quantifies the static deformation of the strings against a forced displacement inputs. The string is modelled as a elastic cord intersecting with each other. Displacements of the cross points of the cord with forced displacement input was caluculated by using an equation which simulates the deformation of the cord.
