摘要： 该文研究了行人与某微型轿碰撞时，车行人动力学响应和损伤风险。以40 km/h 的速度碰撞
时，行人采用 高165 cm，体质量65 kg 的人体有限元模型THUMS，分析了下肢弯矩和膝关节弯曲角度、
胸部碰撞速度、头部碰撞速度和头部伤害允许指标HIC 等人体损伤参数。结果表明: 行人大腿、小
腿弯曲及膝关节弯曲角度小于行人损伤耐受限度。由于与刚性较高的风挡玻璃下隔板碰撞，行人上胸
部肋骨和肩胛骨存在骨折风险。虽头部碰撞速度为10.4 m/s, 但头部与刚度较低的风档玻璃碰撞，头
部损伤风险小。因此，行人与类似微型轿车的前部结构发生碰撞时，损伤风险较小。

Abstract: Dynamic response was investigated for pedestrian struck injury risk ina minicar collision. Vehicle
collisions were simulated using a total human finite element model (THUMS) at speed of 40 km/h with a dummy
of 165 cm and 60 kg. The injury parameters analyzed includes low extremity bending moment, knee joint
bending angle, chest impact velocity, head impact velocity, and head injury criterion (HIC). The results show that
all of the high bending moment, the lower leg bending moment, and the knee bending angle are lower than that
of the injury acceptance levels; both the upper thorax and scapula are at fracture risk due to the impact by the
cowl area having a relative high stiffness structure; and that the head injury risk is low with head impact velocity
of 10.4 m/s, because the impact location is windshield with lower stiffness. Therefore, the injury risk is low when
pedestrian is hit at front conformation for a similar mini car.

Key words: vehicle safety, mini car, pedestrian protection, finite element analysis, total human model for safety (THUMS)
