Abstract:

The compatibility of car-to-car frontal crash was analyzed and evaluated for two types of vehicles
using a full width deformable barrier (FWDB) test method to reduce the high casualty rate in traffic accident.
A finite element model of FWDB was established based on a program by European Enhanced Vehicle Safety
Committee-Working Group 15 (EEVC-WG15). The model was validated using a sled test method by Transport
Research Laboratory (TRL) in UK. Two parameters, the average height of force position and the equivalence
crush-work stiffness, were introduced as the main evaluation criteria for the FWDB crash analysis with car-tocar
100% overlap frontal crash being used to verify the simulations. The results show that the analysis results by
the FWDB crash test are consistent with those by the car–to-car impact. Therefore, the FWDB test method can
represent car-to-car compatibility and can provide efficient strategies for improving vehicle crash compatibility.
