The purpose of this study was to assess the protective capacity of an ice hockey goaltender helmet for three concussive impact events. A helmeted and unhelmeted headform was used to test three common impact events in ice hockey (fall, puck impacts and shoulder collisions). Peak linear acceleration, rotational acceleration and rotational velocity as well as maximum principal strain and von Mises stress were measured for each impact condition. The results demonstrated the tested ice hockey goaltender helmet was well designed to manage fall and puck impacts but does not consistently protect against shoulder collisions and an opportunity may exist to improve helmet designs to better protect goaltenders from shoulder collisions.
本研究的目的是评估冰球守门员头盔对三次脑震荡撞击事件的防护能力。使用佩戴头盔和未佩戴头盔的头模来测试冰球中三种常见的撞击事件（跌倒、冰球撞击和肩部碰撞）。测量了每种撞击条件下的峰值线性加速度、旋转加速度和旋转速度，以及最大主应变和冯·米塞斯应力。结果表明，测试的冰球守门员头盔在应对跌倒和冰球撞击方面设计良好，但不能始终有效地防止肩部碰撞，可能有机会改进头盔设计，以更好地保护守门员免受肩部碰撞。
