Frontal Crash Tests - A Comparison of Methods

Frontal collisions account for the majority of car accidents. Regulations have been in effect since the late sixties, aiming at assuring a basic safety performance for cars in this type of crash.

From a legislative point of view tests as e.g. FMVSS 208 are about to be complemented by other frontal impact configurations. Two of the reasons behind this is to allow assessment also of asymmetric loads to the vehicle front and the level of passenger compartment intrusion.

This paper offers a comparison of different frontal crash tests, including Volvo's Severe Partial Overlap Collision (SPOC) and offset tests against a deformable barrier. The methods are evaluated with respect to their results, both from a dummy performance point of view and based on car deformation characteristics. Also, the practicability and possible effect on vehicle designs are discussed.
