摘要:

通过NHTSA和IIHS真实正面碰撞试验数据的统计和归纳,以及解析求解,分别建立采用C-NCAP评价的100%正面刚性壁障(FRB)碰撞和50%正面可渐进变形移动壁障(MPDB)偏置碰撞,以及采用中国保险汽车安全指数(C-IASI)评价的正面小重叠度壁障(SOB)偏置碰撞中碰撞波形和侵入量的评价方法,可为约束系统的匹配打下良好基础,为车辆获得优异的星级提供保障。

关键词: 正面碰撞, 碰撞波形, 碰撞等级预估

Abstract:

Through the statistics and summing-up of real frontal crash test data in NHTA and IIHS and analytical solving, an evaluation method for the impact waveform and intrusion in 100% overlap frontal rigid barrier (FRB) crash and 50% overlap moveable progressive deformable barrier (MPDB) offset crash evaluated by C-NCAP, and frontal small overlap barrier (SOB) offset crash evaluated by C-IASI (China insurance automobile safety index) is established, which can lay down a good foundation for the matching of occupant restraint system and provide assurance for vehicles to obtain excellent star grade.

Key words: frontal crash, crash waveform, crash grade prediction
