Pedestrian injuries in traffic accidents represent a global public health challenge. Automotive front bumper design plays a critical role in pedestrian safety. This research employs FEA, virtual crash testing, and topology optimization. A pedestrian biomechanical model was tested per Euro NCAP at 40 km/h, comparing five bumper geometries. Split-level geometry reduced head injury risk by 34% (HIC: 850→560) and thorax injury by 28% (VC: 1.2→0.86 m/s). Topology optimization reduced mass by 18% and improved aerodynamics by 5%. A three-tier implementation strategy was developed for Uzbekistan automotive manufacturers.
