The objectives of this research project were first to generate experimental kinematic response and injury data resulting from axial (superior-inferior) head impacts, then to use the generated results to establish a head/neck tolerance level to be used in the design and testing of protective industrial helmets. Fourteen impact tests were conducted on cadaveric specimens. parameters of impact were the impactor weight (10 kg), its velocity at impact (7 to 11 m/s), padding of the impactor (0- to 5-cm ensolite), and the neck alignment with the spinal column. Peaks of the impact force ranged from 3 to 17 kn. Measured responses were the head 3-D motion and the spinal column accelerations.
