Research on vehicle aggressiveness evaluation based on full frontal crash test

Abstract

In the frontal accident, vehicles with strong aggressiveness are an important factor in causing death or injury to vulnerable vehicles. To effectively evaluate the aggressiveness of vehicle frontal crash, the dynamic load values and distribution of vehicle frontal structures are collected using the load-cell wall. On this basis, evaluation intervals in the horizontal and vertical directions are established, and the standard deviation and negative deviation of collision loads were analyzed. Normalization is carried out to establish evaluation indices for horizontal and vertical load effects. The effectiveness of the evaluation indexes is verified through analysis of frontal collision tests on several vehicle models. The results showed that the vertical and horizontal collision energy transfer at the front end of the vehicle still needs to be strengthened.
