Scattering of a baseball by a bat
A ball can be hit faster if it is projected without spin, but it can be hit farther if it is projected with backspin. Measurements of the tradeoff between the speed and spin for a baseball impacting a baseball bat are presented. The results are inconsistent with a collision model in which the ball rolls off the bat and instead imply tangential compliance in the ball, the bat, or both. If the re...
متن کاملBaseball studies: baseball bat testing protocol development
The performance testing of baseball bats for potential use in regulating bat performance is best completed using the same baseballs as are used in a game. In the current research, the effects of repeated use of baseballs in testing are explored. The batball performance is compared with ball performance off a rigid wall, and the consistency of both batand ball-performance metrics during bat-ball...
متن کاملA Comparative Study of Baseball Bat Performance
The results of a comparative study of five aluminum and one wood baseball bats are presented. The study includes an analysis of field data, high-speed laboratory testing, and modal analysis. It is found that field performance is strongly correlated with the ballbat coefficient of restitution (BBCOR) and only weakly correlated with other parameters of the bat, suggesting that the BBCOR is the pr...
متن کاملThe sweet spot of a baseball bat
The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. In order to determine how each of the sweet spots influences the ‘‘feel’’ of the bat, measurements were made of the impact forces transmitted to the hands. Measurements of the bat velocity, and results for a freely suspended bat, were also obtained in ord...
متن کاملNumerical analysis of maximal bat performance in baseball.
Metal baseball bats have been experimentally demonstrated to produce higher ball exit velocity (BEV) than wooden bats. In the United States, all bats are subject to BEV tests using hitting machines that rotate the bat in a horizontal plane. In this paper, a model of bat-ball impact was developed based on 3-D translational and rotational kinematics of a swing performed by high-level players. The...
