摘要: 在中国新车评价规程(C-NCAP)中,正面碰撞时胸部压缩变形量是评价车辆安全性的重要指
标之一。正面碰撞试验中不同试验假人的肋骨性能的不一致,可能导致所测胸部压缩数据差异。为了
消除这种差异, 该文研究假人肋骨刚度特性及刚度差异对胸部压缩变形的影响。对于两个50 百分位
的混合Ⅲ(Hybrid-Ⅲ)型男性假人,进行了标定条件下的正碰冲击试验;在计量校准中,修正了胸部
位移传感器的灵敏度系数。结果表明:通过修订灵敏度系数,可以消除肋骨刚度特性引起的试验结果
差异,进而可提高试验的准确性,有力地支持汽车约束系统的研发。

Abstract: Thorax compressed distortion in frontal crash tests is an important appraisal for vehicle safety
according to the China New Car Appraise Program (C-NCAP). In current frontal crash dummy tests, different
rib inconsistent performance may lead to different data of the thorax compression. This paper investigates the
influence of dummy rib stiffness characteristics and their differences on the chest compression deformation
through calibrating frontal impact tests for two 50th percentile Hybrid-III male dummies, and revising the
sensitivity coefficient of chest displacement sensors in the calibrating measurement. The results indicate
that revising sensitivity coefficient can eliminate the differences caused by rib stiffness characteristics.
Therefore, this method can improve the test accuracy, strongly supporting the vehicle constraint system
development.

Key words: vehicle safety, frontal impact, dummy rib, rib stiffness, displacement sensor, sensitivity coefficient, vehicle constraint system
