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。 In order to design a seat that can protect the neck of an occupant, two different occupant models, BioRID Ⅱ and THUMS, were used in the whipping test to study the neck injury. According to the rules and scoring principles of whipping test in the 2015 edition of China New Car Evaluation Rules (C-NCAP), a finite element simulation model of seat whipping test was established; the dynamic response of these two models and the status of human neck injury were established. The results show that the THUMS model has a higher biological simulation degree, and its neck injury index (NIC), neck shear force, neck torque and upper cervical tension are greater than that of BioRID Ⅱ model. The results provide a reference for improving and improving the biological simulation degree of BioRID Ⅱ model.
