摘　　要：《汽车对行人的碰撞保护(征求意见稿)》(GB24550-202X)将于2024年7月1日起实施。基于该法规,本文对某轻型汽车行人保护下腿部性能的仿真模拟和FLEX-PLI腿型试验进行研究,并对试验结果进行分析确定改进方向,降低MCL位移以实现降低伤害的目的。结果表明,增加了小腿保护梁的前保对减轻行人在车辆碰撞事故中下腿部伤害具有积极意义。GB 24550-202X"Protection of Pedestrians from Collisions by Vehicles(Draft for Comments)"will be implemented from July 1,2024.This article conducts a study on the simulation and FLEX-PLI leg shape test of the leg performance of a light vehicle under pedestrian protection based on this regulation,and analyzes the test results to determine the direction of improvement,reducing MCL displacement to achieve the goal of reducing injuries.The results indicate that adding the front bumper of the calf protection beam has a positive significance in reducing pedestrian lower leg injuries in vehicle collision accidents.
