车辆前端造型对行人胸部损伤影响研究
Study on effect of vehicle front-end styling on pedestrian thorax injury
摘要
Abstract
To study the injury mechanisms of pedestrian thorax and the influence of vehicle front-end styling on such injuries,this paper sets up 30 simulation cases of vehicles with different bonnet leading edge heights(BLEH)and bonnet angles(BA)colliding with THUMS pedestrian models in various postures.It extracts the thorax impact velocity and calculates the thorax injury risk by rib strain.The results show that the pedestrian's movement pattern and the injury site of the thorax are different when vehicles of different BLEH collide with the pedestrian.The BLEH of 950 mm is the switching point of the two motion modes of the pedestrian in the full-body toppling condition and the full-body pushing condition.With the increase of BLEH,the impact speed of the thorax and the injury risk of the thorax first decrease and then increase.Conversely,as BA increases,both the impact thorax speed and the injury risk increase.Additionally,this paper analyzes the impact of vehicle front-end styling on pedestrian thorax injuries,and the results can provide some reference for vehicle safety design.关键词
