The purpose of this research was to examine how four different types of baseball helmets perform for baseball impacts when performance was measured using variables associated with concussion. A helmeted Hybrid III headform was impacted by a baseball, and linear and rotational acceleration as well as maximum principal strain were measured for each impact condition. The method was successful in distinguishing differences in design characteristics between the baseball helmets. The results indicated that there is a high risk of concussive injury from being hit by a ball regardless of helmet worn.
本研究的目的是，当使用与脑震荡相关的变量来衡量性能时，检验四种不同类型的棒球头盔在应对棒球撞击时的表现。一个佩戴头盔的Hybrid III头模受到棒球撞击，针对每种撞击情况测量线性和旋转加速度以及最大主应变。该方法成功区分了棒球头盔在设计特点上的差异。结果表明，无论佩戴何种头盔，被球击中都存在很高的脑震荡损伤风险。
