Badminton shuttlecock is light mass, which is strongly influenced by air resistance and that the wing of the skirt can be easily broken. The highest initial velocity of the shuttlecock exceeds 300km/hr for a professional badminton player. In the present study, the shooting performance of the badminton machine developed by the author is examined. Finite element models of a feather shuttlecock and the badminton machine with two rollers are made, and the shooting simulations proceed with the moving behavior and contact stress of the shuttlecock. The coefficient of friction is examined from the surfaces in contact with the shuttlecock and the roller in the analysis. From the analysis, it is shown that the roller with a small diameter attains the lower speed of the shuttlecock than the other rollers for every shot. The taper angles of the roller edge and the insert height of the shuttlecock are optimized that the shuttlecock speeds are maximized by the shooting simulation and the response surface approach. The validity of the optimum condition is confirmed by the corresponding shot experiments using the two-roller type badminton machine.
