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. © 2019 China Safety Science Journal.
