Tóm tắt:TÀI LIỆU THAM KHẢO:This study employs HyperMesh and LS-DYNA software to conduct a full-frontal crash simulation in accordance with NHTSA (NCAP, USA) standards for the bumper system of an MPV vehicle segment. Three bumper design concepts - Model 1, Model 2, and Model 3-were analyzed under an impact velocity of 56 km/h (35 mph) against a rigid barrier. The evaluation, based on acceleration response and internal energy distribution, indicates that Model 3 demonstrates the highest energy absorption efficiency, followed by Model 1 and Model 2.
