摘　　要：阐述了正面、侧面碰撞试验中常用的试验壁障对不同尺寸车辆相容性的影响。汽车在碰撞中前部所产生的破坏力的最大值是衡量车辆相容性的一个重要指标,根据力学原理,使用固定壁障会导致大型车辆前刚度变大,从而加剧大型车辆与小型车辆间相容性变差。相关文献指出,车辆前部在碰撞中产生破坏力的最大值与试验车的自身质量成正比。通过已有的碰撞数据,确定了车辆NCAP等级与乘员死亡率的关系。This paper describes the effect that test barriers currently used for frontal and side impact tests have had on collision compatibility between different-sized vehicles. The peak force levels generated by the vehicles＇ front structures during the impact test are one of the significant factors in determining vehicle compatibility. It is shown from principles of mechanics that the use of fixed barriers as a test device may lead to higher force levels for front ends of larger vehicles and thus increase the incompati- bility between large and small vehicles. Review of data from various sources supports this conclusion that the peak force levels of vehicles＇ front ends have increased in proportion to their test mass. Available crash data is also examined for a relationship between NCAP ratings of vehicles and the likelihood of serious and fatal injuries to occupants of those vehicles.
