This work identifies the characteristics of racket design parameters
that influence racket performance. It presents the finite element
analysis of several designs of badminton rackets and compares them to
experimental results for validation. Designing a racket requires a
comprehensive understanding of racket performance characteristics.
Essentially, racket performance is related to the sweet spot, which is
the spot on the racket head that produces the most power and control
when it strikes a shuttlecock. Determining a coefficient of restitution
can help to identify the sweet spot on a racket. By analyzing several
head shape designs, it becomes apparent that isometric head shape
rackets produce better coefficients of restitution compared to oval and
round ones. It is recommended that the racket design consist of low
string tension, stiffer racket shafts and bigger head size in order to
produce higher shuttlecock speed.
