摘要: 为降低人车正面碰撞事故中男性行人的损伤程度,利用放缩法建立我国50百分位男性身高168.5cm,体质量为50.5、65.5、75.5、80.5 kg等4种体型的男性行人模型;在MADYMO仿真分析环境中建立上述不同体型的男性行人与运动型多功能车(SUV)在不同碰撞速度、不同最大制动减速度下的正面碰撞模型,开展仿真试验,研究碰撞后男性行人运动形态和头部损伤情况。结果表明:碰撞车速决定碰撞后男性行人运动形态,且显著影响男性行人头部损伤来源;碰撞车速为30~80 km/h,男性行人头部损伤主要是与地面碰撞所致;碰撞车速大于90 km/h,男性行人头部损伤主要是与SUV碰撞所致;男性行人体型越肥胖,与SUV碰撞所致的头部伤害指标值(HIC)越小;最大制动减速度越大,男性行人与SUV碰撞所致的头部HIC值越小,头部与SUV碰撞时刻越晚。

Abstract: In order to reduce the damage to male pedestrian in pedestrian-SUV collision accident, the Hybrid III 50th dummy was taken as the reference model, four types of male pedestrian model of our country with height of 168.5 cm and weight of 50.5 kg, 65.5 kg, 75.5 kg and 80.5 kg were established by scaling, a front collision model of different types of male pedestrian-SUV with different collision speeds and maximum braking deceleration was built by using MADYMO, then computer simulation tests were carried out, to study the movement form and head injury of male pedestrian after the collision. The research shows that the collision speed determines the movement pattern of pedestrian after the collision, that the collision speed has a great influence on the source of male pedestrian head injury, that when the collision speed is 30-80 km/h, male pedestrian head injury is mainly caused by the collision with the ground, when the collision speed is greater than 90 km/h, male pedestrian head injury is mainly caused by collision with SUV, that the bigger the human body type is, the smaller the HIC value of the head caused by the collision with the SUV will be, and that the larger the maximum braking deceleration, the smaller the HIC value of the head caused by the collision between the male pedestrian and the SUV and the later the collision between the head and the SUV will be.

Key words: frontal collision, movement form, head injury criterion(HIC), body feature, maximum braking deceleration, sport utility vehicle(SUV), MADYMO
