摘要:

为对比“一段式”与“分段式”加载方法在模拟“AEB +碰撞”工况下的乘员响应差异,该文在验证车辆约束系统模型和对比Hybrid Ⅲ与THOR假人自动紧急制动系统(AEB)制动离位响应基础上,分别构建2种加载方法的“AEB+碰撞”仿真模型,对比假人运动学与损伤响应。结果表明:“分段式”加载方法下假人头部、胸部及髋部的前向与侧向位移整体大于“一段式”,2种加载方法在头部HIC15和3ms合成加速度、颈部损伤指标Nij等指标上差异较小(< 7%),但在颈部弯矩、胸部压缩速率及粘性指标(ηVC)指标上差异显著(17%~31%)。鉴于“一段式”和“分段式”加载在假人关键损伤指标上不可忽略的偏差,建议一体化安全虚拟测评中采用“一段式”加载。该文的研究结果能为主被动安全一体化虚拟测评方法的选取与规程制定提供定量依据。

Abstract:

To compare the differences in occupant responses between the prevalent “one-stage” and “multi-stage” loading methods under “AEB+crash” conditions, this study validated the vehicle restraint system model and compared the out-of-position responses of Hybrid III and THOR dummies under autonomous emergency braking (AEB) loads. On this basis, “AEB+crash” simulation models were constructed for both loading methods, and the differences in dummy kinematics and injury responses were compared. The results show that the out-of-position responses of the THOR dummy under braking are closer to those of the human body, making it more suitable for integrated assessment. Under the “multi-stage” loading method, the forward and lateral displacements of the dummy's head, chest, and pelvis are generally greater than those under the “one-stage” method. The differences between the two methods are relatively small (<7%) in terms of HIC15, 3 ms resultant acceleration, and neck injury indicators (Nij), but are significant (17%-31%) in neck bending moment, chest compression rate, and viscous criterion (ηVC). Given the non-negligible discrepancies in key dummy injury indicators between the “one-stage” and “multi-stage” loading methods, it is recommended that the “one-stage” loading method, which better reflects the actual mechanical process of real-world accidents, be adopted in integrated safety virtual assessment. The findings of this paper provide a quantitative basis for the selection and procedural standardization of integrated active and passive safety virtual assessment methods.
