| Abstract | With the popularity of baseball, numerous studies have been conducted to find methods to improve performance during a baseball match. However, it's still unclear that how the batter should hit a ball so that the batted ball speed is largest. In other words, where is the sweet spot that maximum energy is transferred to the ball when it's hit? In this paper, we take three factors into consideration to deter-mine position of sweet spot. We build three models to confirm corresponding factors: (1) relationship between batted ball speed and distance from hit point to pivot point when the pivot point is fixed, (2) loss of energy caused by vibration of bat, (3) loss of energy caused by rotation of bat. At last, by considering the above three models to get the final energy of ball. We find that the COP(Center of Percussion) point is just the sweet spot. At last, by statistical processing to results of baseball match in the last more than 30 years, we find that the aluminum bat shows a marked increase in hit-ball speeds. In addition to that, we also give reasons why Major League Baseball prohibits metal bats according to our model. |
