Baseball best batting point to batting efficiency optimization model analysis based on rigid body dynamics

ShanliYi

Baseball is a kind of collective, highly confrontational ball sports event thatmain characterized as playing ball by bat. It is widely developing in the world with great influences, which is honored as “competitiveness and intelligence combination”. Baseball players divides into attack, defense the two parties, using bat and gloves, they play game in a fan-shaped baseball field. In game, two parties alternate attacking, when attacker successfully runs back to home base, he can get 1 score. Highest score team in nine innings wins the game. To get high score, besides relying on athlete himself technique and physical quality, it should also find out baseball bat batting best position achieved high score. This paper, with regard to batting best position, it makes systematically analysis in theory and experiments. It includes applyingmomentumconservation law, angular momentum conservation law and restitution coefficient, optimal solution, establishes rigid body dynamical model to research on baseball batting process, and by impact center concept, it solves baseball bat batting best position.
