Human Head and Neck Response to Impact Acceleration.
Abstract
A methodical investigation and measurement of human dynamic response to impact acceleration was conducted. Linear accelerations were measured on the top of the head, at the mouth, and at the base of the neck. Angular velocity was also measured at the base of the neck and at the mouth. A redundant photographic system was used for validation. All data were collected in computer-compatible format and data processing was by digital computer. Selected data analysis on 41 representative human runs involving 12 subjects of the 236 human runs completed to date are presented. Description of the experimental design, data collection and processing is given in detail. Ancillary research efforts in support of the program are also described. Representative plots of the human kinematic response are presented, discussed, and compared. Repeatability and quality control plots are alos presented. There are a total of 755 computer drawn plots illustrating a characteristic, repeatable response of human subjects to impact acceleration. (Author)
