Measurement of 6 Axis Force/Torque and Estimation of Point of Application at Each Grip During Golf Swing

Abstract

Golf club is manipulated by both hands and arms which consist closed link structure. Since the closed link structure can move fast the club and transfer the energy of trunk and lower body into the club directly, it is important to understand how golfer manipulates the golf club using both arm forces and torques acting at each grip. However, it is hard to solve inverse dynamics problem of this system without measuring each right and left arm or each grip force. In this study, the manipulating forces which act at both grips during golf swing were measured using a 6 axis force/moment sensors and points of application of forces at each hand were identified.
