| Abstract;It is desirable for the design of a baseball bat to analyze exactly the phenomena of the impact between baseball and bat. In order to establish powerful analytical tool for the baseball-bat impact, the numerical analysis programs based on 3-dimensional finite element method are developed. After the calibration of developed programs due to the comparison between calculated and experimental results, the impact characteristics of an aluminum bat for rubber-ball baseball are investigated precisely. It is found that the COR value decreases as the impact velocity increase and it is deeply affected by the hoop rigidity of the cylindrical shell structure in bat. (author abst.) |
