Inducing collision of vehicles with the incompatible energy consumption of bodyworks in deformation zones

Abstract

In the field of automotive safety, both geometrical and energy compatibility [5] of bodyworks is one of the issues. While inducing collision of vehicles with different sizes and mass, breakdowns of “smaller” vehicle may occur. For this reason, correctly designed automobiles have elements put at the same height, which are consuming energy while confronting, both bumpers, and elements of the zone of the controlled crumple. On account of limited dimensions, vehicles cannot have an effective zone of the controlled crumple from the side. At hitting with the front part of the vehicle in the side of another vehicle, most often deep deformations of the structure of the bodywork are reached and as a result of it - serious injury of passengers which were in the vehicle. In the article reconstruction of the road event was shown, consisting in hitting with the front part of the vehicle Volkswagen Golf into the side of the vehicle Mercedes. As a result of the accident the driver of one of the vehicles died, however the driver and the passenger of the second vehicle, despite of the high speed of the vehicle, didn't sustain injuries. The analyzed case is the example of the collision of vehicles with incompatible energy structures in the place of their contact. Repeatedly, the higher stiffness of the front part of the vehicle and the zone of the controlled crumple assured safety for its passengers, with the cost of the safety of the driver of the second vehicle. During the reconstruction of the event, the method of calculation leaning against the Burg model, modified on account of the movement of one of the vehicles all over the road surface with variable mechanical properties, was applied.
