Baseball 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 کاملScattering 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 کاملDynamics of the baseball–bat collision
A model is developed for the collision between the baseball and bat, taking into account the transverse bending vibrations of the bat. By coupling the flexible bat to the ball via a parametrized force that each mutually exerts on the other, a complete description of the collision process is obtained, including the exit speed of the ball v f . It is shown that vibrations play an important role i...
متن کاملExperimental Investigation of Youth Baseball Bat Performance
Abstract: The batted-ball performances of youth wood and nonwood bats are examined through experimental methods. The goals of the study are to build a database of performance data on youth bats using a hitting machine in a controlled laboratory environment and to examine how the lab data compare using three performance metrics including the current BPF certification metric. The performance metr...
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...
