摘要/Abstract

摘要：

首先，采用Hybird III假人和CHUBM人体模型搭建了50 km/h速度下正面100%刚性壁障虚拟碰撞仿真平台。然后，建立了Hybird III假人座椅在A位置与CHUBM人体座椅分别在A和B位置的整车碰撞有限元模型，并对3种情况下驾驶员的头部、胸部及大腿损伤进行了对比分析。结果显示：座椅A位置的Hybird III假人和座椅B位置的CHUBM人体动态响应具有较好的一致性，不同座椅位置下的CHUBM人体的头部、胸部损伤均比Hybird III假人的高；CHUBM人体在座椅A位置的损伤比B位置的要高，同时肋骨发生了骨折现象。研究结果表明：CHUBM人体模型具有更加真实的人体解剖和仿生逼真度，对汽车约束系统的安全性评价要求更高，可为汽车安全性设计提供相应参考。

Abstract:

First， the Hybird III dummy and CHUBM human were used to build 50 km/h frontal 100% rigid barrier virtual collision simulation platform to conduct preliminary exploratory study. Then，three finite element models of the vehicle collision were established under the Hybird III dummy seat position A and CHUBM human seat position A and B. And three cases under the driver's head， chest and thigh injuries were compared by analysis in simulation. The results showed that Hybird III dummy of seat position A and CHUBM human of seat position B had a good consistency in the dynamic response. The head and chest injuries of CHUBM human under different seat positions were higher than Hybird III dummy. The injury indicators of CHUBM human at seat position A were higher than that at seat position B， and the fracture of human ribs was occurred. The research results show that the CHUBM human has more realistic human anatomy and bionic fidelity， and has higher requirements for the safety evaluation of vehicle restraint systems， which can provide corresponding reference for the safety protection design of vehicle.
