In order to evaluate baseball bat hitting performance, many kinds of test methods have been developed and several bat support devices have also been employed. However, the influence of the support methods on the coefficient of restitution has not been clarified yet. In this report, we developed a finite element model of hard baseball designed with static mechanical property and coefficient of restitution onto rigid wall. Some numerical analysis on hitting the baseball with a metal bat have been carried out by using three kinds of clamping devices for bats, that is, "rigid clamp", "rotating-free clamp", and "free support". We concluded that differences in clamping method of metal baseball bat scarcely affected evaluating results of coefficient of restitution because of very short contact time in case of hard baseball.
