Abstract: With the iteration of vehicle brand design, the applicability of the current Mobile Progressive Deformable Barrier (MPDB) scheme has declined. The Advanced Chinese Mobile Progressive Deformable Barrier (AC-MPDB) is introduced, which incorporates segmented Z-directional design and increased mass distribution to better align with the Chinese vehicle front-end structure. This study utilizes Camry and Rogue models to design an MPDB-to-vehicle and a vehicle-to-vehicle simulation matrix. The compatibility of the barrier schemes, Euro-NCAP MPDB (E-MPDB) and AC-MPDB, is evaluated using energy equivalent speed, occupant load criteria, peak force, and acceleration. The simulation results indicate that, compared to E-MPDB, the AC-MPDB barrier scheme exhibits excessive stiffness for medium-sized sedans with smaller mass but demonstrates better compatibility with SUVs. Further analysis of the target vehicle's longitudinal beam deformation animation and pedal intrusion reveals that AC-MPDB achieves superior vehicle reproducibility, particularly for SUVs.
