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3011,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。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 3011,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.
