ENERGY BASIS FOR COLLISION SEVERITY
This paper presents an objective technique for estimating the severity of automobile collisions. The vehicle damage and the dynamic force-deflection characteristics of the vehicle structure are used to estimate the energy absorbed in plastic deformation of the vehicle. The energy can then be expressed as an "equivalent barrier speed" (EBS). Data are presented relating residual crush and impact speed for full frontal barrier tests to provide the basis for a simple model of the force-deflection characteristics of the vehicle front structure. The results of this model are compared with test data to indicate the types of damage patterns for which the model appears valid.
