FRONT AND SIDE CAR-TO-CAR CAE BASED CRASH ANALYSIS OF DIFFERENT CLASS VEHICLES

摘要

In recent years, rapid-increasing market share of compact cars and SUVs has brought for both consumer and automaker to pay more attention on crash compatibility between the compact passenger vehicles and the light trucks (i.e., Pickups and SUVs). Vehicle compatibility regarding both self and partner protection in frontal crash of different class vehicles is one of hot issues in vehicle safety. Furthermore, it is expected that the amendment of UNECE-Regulation 94 to implement compatibility issues in couple of coming years. This paper presents front and side car-to-car CAE based crash of different class vehicles which describes a car accident in real field. Structural engagement and energy balance of different class vehicles in front and side carto- car crash are identified. In this study, conceptual design of compatibility compliant frontal vehicle structure which subjects to improve the distribution of frontal crash loading and structural engagement between vehicles is introduced. The effects of proposed vehicle structure on possible candidates (i.e. FWRB, FWDB and PDB) for a compatibility evaluation test procedure and car-to-car crash are also investigated.
