Abstract
Road traffic accident-induced traumatic brain injury is a critical health concern. Understanding the biomechanics of the head during accidental impact is important for devising impact mitigation and injury prevention strategies. In this work, we reconstruct the specific case of collision of the vehicle with pedestrian using the pendulum impactor setup. The surrogate head was used for studying biomechanical response. The surrogate head consisted of a hollow polycarbonate spherical shell filled with water. Dummy neck is also considered in the form of a spring. Head acceleration, skull strain, and intracranial pressures (ICPs) were measured. Using this setup, we were able to recreate head kinematics and kinetics that are implied during these accidents. The measured biomechanical response is consistent with the findings in the literature. The work provides novel insights into the biomechanics of road traffic accident-induced brain injury.
