Converting post-crash deformation into energy equivalent speed (<i>EES</i>): Toward an objective measure of crash severity

In this paper, an objective method for the conversion of post-crash vehicle deformation to crash energy is presented. While severity assessment standard test configurations relatively robust, bias in real-world reconstruction a well-known problem. A reduce constructed by focusing on deformation, principle direction force ( PDOF), and type VT) only. The analysis was restricted 12 PDOF six VT. voxel model, onto which depth information deformations mapped, every Standardized tests were used normalize assigned each voxel. plastic computed integrating across all deformed voxels. This expressed as “energy equivalent speed” EES). allows retrospective calculation EES from deformations. Thus, values can be databases like CISS or GIDAS even legacy NASSCDS. results model will become part database. tested using car-to-car test, 40% offset frontal-frontal collision Audi Q7 against Fiat 500.
