Full Width Deformable Barrier (FWDB) finite element model is established according to the standard of EEVC-WG15, calibrated using the Transport Research Laboratory (TRL) trolley experiment method, and the Moving Progressive Deformable Barrier (MPDB) finite element model that has been calibrated and verified is used to build the MPDB and FWDB crash models of cars and SUVs respectively for the frontal collision compatibility study of vehicles. Compatibility evaluation indexes of MPDB and FWDB models are calculated, the analysis results show that the current MPDB conditions have some limitations on the evaluation of structural compatibility of vehicles, and cannot evaluate the role of the primary energy absorbing structure in the vertical and horizontal directions, and need to be combined with the compatibility evaluation indexes of FWDB conditions, VSI and HSI, to conduct an analysis in order to evaluate the frontal collision compatibility of the vehicle in a more comprehensive way.
