Side Impact Safety Research Based On A Vehicle Modle

Since the vehicle as the main the transportation traffic safety problems get commonattention and research, all countries in the world try their best to research to improve thevehicle safety performance. More and more laws and regulations on vehicle crash safety beestablish to promote the improvement of vehicle safety performance. Now China has becamethe world’s major automobile producer and consumer, and for this problem people also putsforward the huge requirements to improve the vehicle safety performance.Vehicle side impact safety is one of the main evaluation index of the vehicle crash safety,Vehicle side impact safety include front impact and side impact and behind impact, lateralstructure is a weak automobile part. When the automobile occur the side part easy to crewliving space caused great intrusion, and the invasion speed of the door and B column easy todamage the body of passage. Therefore, for the car side impact of further research to reduceside collision occurs and reduce the traffic accident happens have very important significance.The paper is about the side impact safety performance research base on a new car of adomestic company, through the simulation analysis and real vehicle test combination methodto improve the side impact safety performance of the automobile. And the research accordingto C-NCAP2012analyzed and evaluation deformation, intrusion quantity, intrusion speed anddummy damage and so on.The paper also through analysis and design weak part to improve the vehicle side safetyperformance such an B column, the door and so on. Next combine the software of Madymo toresearch the dummy damage, verify the effectiveness of the improved structure.
