某乘用车行人碰撞安全性的实验研究

Crash Safety Research of a Passenger Car Based on Pedestrian Protection

为了评价某乘用车行人保护的安全性能,介绍了《欧洲新车评价规程》(E-NCAP)和《欧盟行人保护法规》中的关于行人保护的评定方法,对该型乘用车进行了碰撞试验,得到了该型乘用车行人碰撞保护的测试结果。分别建立了保险杠及相关组件对行人腿部保护方面和发动机盖罩对行人头部保护方面的人车模型,分析了行人腿部碰撞结果和行人头部碰撞结果。试验和建模分析得出:该乘用车型行人碰撞保护整体效果较好。

In order to evaluate safety performance of a passenger vehicle pedestrian protection, the evaluation procedures of pedestrian protection in European New Car Assessment Program （E-NACP） and the Pedestrian Protection Regulation of the Eu- ropean Commission were introduced, the pedestrian crash protection tests of the certain type of passenger car were made, the test results of the pedestrian crash protection can be obtained. The pedestrian-vehicle models are established based on the bumper and relative parts design to leg protection and the engine cover design to head protection of the pedestrian. Then the simulation analysis on head crash and leg crash is carried out. The test and simulation analysis results show that pedestrian pro- tections perform well.
