Evaluation of automotive seat for Euro-NCAP rear impact test based on finite element method

Abstract

The vehicle accidents have become more frequent than the past in cities with high population Such collisions will not cause fatal injuries to the occupants The injuries caused are only minor injuries and are often ignored However the whiplash injury of the neck caused by the rear collision causes considerable social costs and has a great relationship with the design of the automotive seat In this study a finite element model of car seats on the market was established and the Biorid II dummy model was added for simulation verification of the rear impact test First carry out the compression test of the foamed cotton and the rear torque test of the car seat and conduct a verification comparison After that according to the test procedure of the European new car evaluation procedure the result of the seat collision after different accelerations was simulated Finally the damage score of the seat is calculated and the simulation of the finite element model is verified
