- 232 On the developments of functional shooting machine of baseball ball with compressed air
抄録
According to the observations of pitched ball in real baseball game and aerodynamic characteristics clarified by wind tunnel experiments, there are many strange changing ball in baseball ball. In this research, special attention was focused on spinning axes direction, which oriented toward boll flight direction. There are no convenient pitching machines to be able to generate such kind of balls, easily. We had developed a pitching machine with pressurized air method into higher functional one, in which be able to generate purely oriented toward boll proceeding direction, with 2 and 4-seams ball arrangements. In this reports, we describe the strange characteristics of such kind of balls, and then some trial developments of the pitching machine. High speed camera images of shooting balls of 2 and 4-seams balls showed the success in this idea.
