Abstract

The invention provides a method for judging performances of vehicle collision structures. By joint use of vehicle collision structure transverse indexes VSIstep1 and VSIstep2 and vehicle collision structure longitudinal indexes HSIstep1 and HSIstep2, accurate quantified testing and judgment of the performances of the vehicle collision structures can be realized; in vehicle design, manufacturers can be guided to pay attention to protect passengers on a vehicle and also reduce damages of the other vehicle in collision, the problem of differences of front-end collision structures of vehicles in the same level or adjacent levels is solve, and vehicle damages in collision of two vehicles are avoided. The method has advantages of extensive vehicle model application range and accuracy of quantified judgment results.

Description

technical field [0001] The invention belongs to the field of vehicle collision safety performance detection, in particular to a method for judging vehicle collision structure performance. Background technique [0002] With the advancement of automobile safety technology, most models can now obtain high scores in NCAP frontal crash tests, but traffic accident statistics show that car-to-vehicle collision accidents are still one of the main causes of occupant casualties. The number accounts for about half of the total number of car accident deaths. Tracing it to its cause is due to the mass, rigidity and geometric shape difference of collision two parties, in this kind of collision accident, the vulnerable party does not have enough protection for its occupant. The root of this problem lies in the lack of technical constraints on vehicle collision compatibility at present, which makes automobile manufacturers pay more attention to the protection of their own occupants and ign...
