Abstract

Abstract: In order to study the characteristics of the rear left passenger injury in car impacting a rigid barrier wall at 60° oblique angle, a finite element model was built for the car, the rigid barrier wall and the dummy by Presys. After calculating by Ls-Dyna, Presys finite element software was used to analyze the left rear occupant damage at 30, 40 and 50 km/h. The results show that with the increase of impact speed,the acceleration on the head and the force on the neck increase, that when the impact speed is 40 per hour, the dummy head Y-acceleration is the highest, and that there is a positive correlation between both the chest acceleration and the amplification of the acceleration increase and the impact speed.

Key words: vehicle oblique crashes, injury response of rear left side passenger, impact velocity, simulation, Presys finite element software
