摘要
为设计出可保护乘员颈部安全的座椅,在鞭打试验中,对BioRID Ⅱ和THUMS两种不同乘员模型,研究了颈部损伤情况。根据2015版中国新车评价规程(C-NCAP)中鞭打试验评价规程和评分原则,建立了座椅鞭打试验有限元仿真模型;对这两种模型动态响应和人体颈部损伤状态。结果表明:THUMS模型有较高的生物仿真度,其颈部伤害指数(NIC)、颈部剪切力、颈部扭矩以及上颈部拉力均大于BioRID Ⅱ模型。该结果可为提高和完善BioRID Ⅱ模型的生物仿真度提供参考。
Neck-injuries were investigated in whiplash test by two different occupant models(the THUMS(total human model for safety)and BioRID II model)to design a better anti-whiplash seat with occupant-neck protection.A seat finite element model was established to simulate whiplash test according to the China New Car Assessment Programme(C-NCAP)(2015Ed)evaluation procedures and principles of whiplash test score.The dynamic responses and neck-injuries were compared for the two models.The results show that the THUMS model has better biofidelity with larger neck injury index(NIC),neck shear force,and the torque and tension on neck than the BioRID II model.These will provide valuable references to improve biological fidelity of the BioRID II model.
