고강도 강판을 적용한 ULSAB-AVC 모델의 충돌성능 평가

Abstract

Achieving the ultra light vehicle is the most essential target to automakers for enhancing the fuel efficiency and confronting the enforced CO2 emission regulations. On the contrary, as the regulation and assessment program for safety of passengers become stringent, automakers are required to develop the lighter and the safer vehicles. In order to fulfill the both requirements conflicting with each other, the application of AHSS(Advance High Strength Steel) such as DP, TRIP and martensite steel have been proposed by the automobile and steel company. For instance, ULSAB-AVC was one of the most remarkable reactions to offer solutions with steel to the challenges facing automakers around the world to increase the fuel efficiency with improving safety, performance and maintaining affordability. In this paper, the crash performance of ULSAB-AVC model according to the US-SINCAP is evaluated with the crash analysis in order to compare the effectiveness of applying the AHSS to that with conventional steels. The crashworthiness with AHSS is verified with comparing the deformed shape of the cabin room, the energy absorption characteristics and the intrusion velocity of the car.
