行人腿型冲击器生物力学响应分析

ANALYSIS OF BIOMECHANICAL RESPONDING OF PEDESTRIAN LEGFORM IMPACTORS

本文对Flx-PLI、Flax-PL/JBM和aPL三种行人腿型冲击器进行了试验结果分析对比,研究了三种腿型冲击器的生物力学响应特性。本文试验中,这三种冲击器对同一款SUV的车辆中央位置和车辆边缘位置分别进行碰撞冲击,试验结果显示FRx-PL在股骨损伤方面存在一定缺陷,在冲击车辆高度较高的SUN试验中,Flex-PlI变形程度与实际情况存在差异。Flx-PL/UBM与aPLI冲击器的运动姿态与变形情况则更贴近实际,各项伤害指标高于Flex-PLI。

Flex-PLI,Flex-PLIUBM and aPLl est results were compaered in this paper,to analyse the biomechanical characteristic of these 3 legform impactors.Tests were performed on center and edge of the same SUV.Results showed that femur injuries of Flex-PLl had inconformity with the actual performance of human body especilly in high height vehicles.Flex-PLI and aPLl resuts showed worse injuries compared with Flex-PLI,deformation and movement of these 2 impactors were very closed to real accident.
