A Comparison of Peak Linear and Angular Headform Accelerations Using Ice Hockey Helmets

CODEN: JAIOAD

Abstract

The objective of this study was to quantify the ability of hockey helmets to manage peak angular and linear acceleration of the center of gravity of a Hybrid III headform at six impact locations and three velocities (5, 7, and 9 m/s). The method was intended to represent a reconstruction of helmet, shoulder, and elbow strikes to the head. Six different ice hockey helmets were impacted using a pneumatic linear impactor at velocities similar to those encountered in ice hockey. The results were then compared to impacts to an unhelmeted headform. The data demonstrated that under certain conditions, peak angular accelerations were above estimated injury thresholds, while peak linear accelerations remained below. This confirmed the importance of measuring peak angular acceleration and peak linear acceleration in order to better predict minor traumatic brain injuries.
