Sensitivity analysis of a Hybrid III head- and neckform to impact angle variations (Abstract)

摘要

Introduction: Snorts helmet standards employ resultant linear acceleration thresholds derived from primate, canine, and post mortem human subject testing. Through the use of sports helmets traumatic brain injury has become rare while the risk of mild traumatic brain injury (mTBI) remains undiminished. Research has identified angular acceleration as an important biomechanical predictor of mTBI: however, a valid and reliable three-dimensional sports helmet testing protocol capable of educing the effect of both forms of acceleration has yet to be developed. The goaf of this investigation is to identify variations in the component linear and angular accelerations of a Hybrid 111 headform elicited by angle modifications to the impacting vector.
