Coefficient of Restitution and Impact Location of a Badminton Racquet

Abstract

The relationship between a shuttle’s point of impact on a badminton racquet and its coefficient of restitution (COR) was investigated. A Yonex Aerosensa 10 shuttle was dropped onto various locations on the head of a horizontally clamped Yonex Voltric Z Force II badminton racquet. Video of the impact was recorded and analyzed to find the COR at each location. Results showed that the highest COR occurs on the longitudinal axis of the frame, specifically at the center and near the base of the racquet frame. Impacts at the side caused frame rotation, decreasing COR. These findings contrast with previous research on tennis racquets, highlighting the different responses of badminton equipment.
