Comparison of Kinematic Parameters Between Hybrid II Head and Neck System with Human Volunteers for -Gx Acceleration Profiles

Abstract

Significant kinematic parameters of the head are compared between a Hybrid II head and neck and human volunteers subjected to the same -Gx sled acceleration profiles. Comparison time profiles between the dummy and human subjects for components of linear acceleration, velocity, and displacement of the head center of gravity and the first thoracic vertebral body (T1) anatomical origin, as well as components of angular acceleration, velocity, and displacement of the anatomical coordinate systems are prsesented for 6, 10, and 15G peak sled acceleration in the -Gx environment. Significant differences between the dummy and human volunteers are discussed in regard to peak values of parameters, time latencies, and overall shape agreement in a time window where motion is significant.
