ABSTRACT
Reconstruction of car accidents is a complex task, with many unknown variables. Among the parameters used to assess the accident severity, in case of a frontal collision between two vehicles, are the change in velocity (delta-v) and the Energy Equivalent Speed (EES). The EES is usually determined based on the deformations. Delta-v can be obtained from the crash pulse recorded with Event Data Recorders, or with crash loggers based on accelerometers, in case of crash tests. In this paper is presented a full scale crash test that involves two vehicles in a frontal collision. The results are obtained using different analysis methods: direct application of a model, processing the measured crash pulse, and computer simulation.
Key Words: Frontal collision, Crash test, Crash pulse, Energy equivalent speed, Delta-v
