In order to increase the existing dataset, three full-scale, rear
impact crash tests were performed. The delta-V for each test was
measured as was the level of occupant movement in the target vehicle.
The main limitation of full-scale crash testing is that the costs
involved constrain the sample size and limit the opportunity for
repeatability. The motion of the subject was analysed by measuring
the acceleration of the head and of the chest. A hypothesis was
tested that there is a correlation between delta-V and head/chest
accelerations. The results from the full scale testing were compared
with previous research in order to investigate the possibility of a
threshold at which collision accelerations are similar to those experienced
in everyday events. Sitting into a chair was proposed as a
suitable every day event for comparison purposes..
