摘要
本文旨在通过组织层面分析C-NCAP鞭打试验中THUMS人体模型颈部的伤害。首先基于C-NCAP(2018版)鞭打试验建立某座椅仿真模型,以医学上的颈部损伤指标作为评价指标对THUMS人体模型颈部进行伤害研究。结果表明,在头部过度弯曲的情况下,颈部各组织的应力应变参数在"C"变形阶段均明显比"S"变形阶段大,软组织损伤更严重,头部的上窜和颈椎过度弯曲都会导致前纵韧带、棘间韧带过度拉伸,易发生撕裂损伤。
The purpose of this paper is to analyze the neck injury of THUMS human model at tissue level in C-NCAP whipping test.Firstly, based on the C-NCAP(2018) whipping test, a FEM model is established. The medical neck injury criteria is used as the evaluation criteria to study the neck injury of THUMS human model. The results show that the stress-strain parameters of cervical tissues in the Cshape of cervical are significantly larger than those in the S-shape of cervical vertebrae, head channeling and excessive bending of the cervical will lead to excessive stretching of the anterior longitudinal ligament and the interspinous ligament, which are liable to tear.
