摘　　要：根据欧洲经济委员会(ECE)推出的R129法规中儿童座椅侧面碰撞保护性能的要求,建立了侧面碰撞台车试验系统。用已有后向碰撞波形发生装置,组合了后向碰撞聚氨酯管、橄榄头、台车初速度,调试波形,实现了侧面碰撞所需的速度波形。按照该法规,设计台车座椅和门板系统,进行Q系列3岁假人模型的侧面碰撞试验,测量了假人头部、胸部损伤,分析了座椅与门板相对速度曲线和碰撞过程的高速摄影图像。结果表明:速度波形符合该法规要求,台车座椅和门板系统位置准确、结构稳定。因而,该台车试验系统,能满足该法规要求,进行侧面碰撞试验。According to the requirements on lateral impact test for child restraint system （CRS） in R129, which was legislated by the Economic Commission for Europe （ECE）, lateral impact sled test system was established Making use of the rear impact velocity wave generation system, which consisted of the polyurethane tube, olive-shaped head, initial crash velocity and adjusting wave profile, desired lateral impact test velocity wave was realized. According to R129, child seat bench and door system were designed, lateral impact tests were performed on the lateral impact sled test system using the Q3 child dummy, the dummy head and chest injury were quantitatively measured, the relative velocity curves of test bench and door components, and the high speed impact video were analyzed. Test results demonstrate that the impact velocity profiles satisfy the requirements of the R129, the positions of test bench and door are accurate, and the structure components are stable. Thus, the lateral impact sled test system meets the standards of R129, and can be used for child seat lateral impact test.
