摘　　要：开发了侧面碰撞乘员胸部、腹部和髋部损伤影响因素分析模型,并经过多工况试验验证。在该模型的基础上研究了侧面碰撞侵入速度、侵入形态以及车门内饰系统刚度特性对乘员损伤的影响。得出结论是:控制侧面结构侵入速度在8m/s以下,在胸部撞击之前推开乘员的髋部(髋部提前)以及适当的车门内饰系统刚度特性,可以显著减轻对乘员的伤害。An analysis model for influencing factors of occupant thorax, abdomen and pelvis injuries is developed and validated by tests under several driving conditions. Based on the validated model, the influences of impact velocity, bari＇ier configuration and the stiffness of door-trim board along impact direction on occupant injuries are studied. The results indicate that impact velocity below 8 m/s, pelvic lead （pelvic impact prior to the impact of the rib cage） and appropriate stiffness of door-trim board can alleviate occupant injuries significantly.
