  • Abstract The purpose of this study is to analyze baseball collision by using finite element method, and investigate batting effect on the sweet spot on the bat and then change the baseball geometry parameter. In addition, the researcher would like to investigate the effect of flight on batted ball by changing swing parameter. LS-DYNA is used to simulate collision on the different position on the bat after using SolidWorks to build modal, then compare the results to locate the exact position of sweet spot on the bat. By building different weight, length and radius of bat barrel, and simulate collision individually, the researcher wishes to investigate the influence of changing bat geometry parameter to batting effect on sweet spot. At last changing the undercut distance and bat swing angle, two of the swing parameter, to simulate collision, and the results of collision are used to get flight trajectory by numerical method, then analyze the influence of changing swing parameter to batted ball range. This study can provide bat geometry characteristic, swing information, and a reference for choosing a baseball bat, even help adjust batting feel for the batter.
