| 摘 要： | 为降低保险费用,要求车辆的主要结构在低速碰撞过程中不会产生永久性破坏。因此,文章基于RCAR试验标准,建立了某车型的低速正面碰撞有限元模型,并通过与试验结果的比较证实模型的有效性。在此模型的基础上,针对该车型在低速碰撞过程中出现的问题,对其前保险杠的吸能盒进行了改进设计,通过系统试验与整车试验,验证了设计结构的有效性,为相关设计提供重要的指导意义。

| Abstract: | There should be no permanent damage on the key component during the low speed impact in order to decrease the insurance costs.Based on the RCAR requirement,a vehicle finite element model during the low speed impact is established,which is validated through comparing with the test results.Based on this model,for improving the vehicle low-speed collision performance,its front bumper crash can is modified.The effectiveness of the improved structure is verified through sub-system test and vehicle test,which pro... |
