摘要:

为提高车辆在真实事故中的安全性能,进行了非法规侧面碰撞工况下乘员的运动学响应及损伤风险研究。建立了2款车型(轿车和运动型多用途汽车SUV)在3种碰撞工况(前角碰撞、斜角碰撞、中部碰撞)中与轿车侧面碰撞的有限元仿真模型;采用Abaqus全球侧碰假人WorldSID的50th男性假人。结果表明:不同碰撞工况对近端、远端乘员运动学响应和头部、胸部损伤均有显著影响;在SUV-轿车-斜角碰撞工况下,远端乘员头部损伤风险远大于近端乘员,其中头部伤害指标HIC15值达3 011,远超严重损伤限值700;在SUV-轿车-中部碰撞工况下,近端乘员的胸部压缩量57.5 mm,腹部压缩量为88.7 mm,均超过损伤限值。

Abstract:

The kinematic response and the injury risk of occupants in non-regulatory side-impact conditions were investigated to improve the safety performances of vehicles in real accidents. A Finite element simulation model for two types of vehicles (sedan and SUV (Sports Utility Vehicle)) in three collision conditions (the front-angle collision, the oblique-angle collision, and the mid-range collision) with the sedan's side collision was established using the 50th male dummy of WorldSID (Abaqus Worldwide Side Impact Dummy), and the global side-impact dummy of Abaqus. The results show that different collision conditions have significant effects on the proximal and distal occupant kinematic responses and the head and chest injuries; In the SUV-sedan-beveled-angle collision conditions, the risk of head injury for the distal occupant is much greater than that for the proximal occupant, in which the head injury index, HIC15, reaches 3 011, which is far more than the severe injury limit of 700; In the SUV-car-center collision condition, the chest compression of the near-end occupant is 57.5 mm and the abdominal compression is 88.7 mm, both exceeding the injury limit value.
