801 2次元スイング中のゴルフクラブの挙動解析

抄録

Composite materials have been employed in many sporting gears. Especially, laminated composite materials are used for the golf club shafts. The purpose of study is to present the two-dimensional swing simulation of the golf club refereeing the swing image of the golf swing robot to clarify the deflection of the swinging golf club shafts. Firstly, a finite element model of golf club which consists of the simplified golf club head and the laminated composite shaft is presented. And, it is proposed that the two-dimensional swing simulation of the golf clubs using the relationship between the time and the angular velocity of the grip of golf club estimated from the swing image of the golf swing robot. Next, from the results obtained by the proposed swing simulation, the validity of the grip position of the golf club is clarified. Finally, the effects of the stacking sequence of the golf club shaft and the swing speed to the deflection of the shaft during the swing are examined, respectively.
