Determination of Crashworthiness in Full Frontal Car/Car Collisions by Fixed Rigid Barrier Testing

Three groups of crash tests were analyzed to determine how well the standard fixed rigid barrier measures potential crash survivability in small cars when impacted full frontally by larger cars. In addition to experimental results, simple analytical methods were used to determine and compare the level of occupant protection in the small cars. The fixed rigid barrier appears to be an accurate crashworthiness-measuring device for small cars in high speed full frontal car/car collisions, if test velocities are selected on the basis of equivalent energy between car/barrier and car/car collisions as opposed to equivalent momentum.
