2020版E-NCAP MPDB碰撞研究

Research on 2020 E-NCAP MPDB Test

2020版E-NCAP将采用MPDB碰撞替代现行的ODB碰撞工况。为研究新工况下的车辆碰撞安全性,采用仿真分析手段,以不同重量的车型为研究对象,开展包括OLC、SD以及击穿罚分的分析,寻求相应的设计策略。研究表明:新工况对小质量车型及大质量车型的影响较大。针对分析结果,总结出相应的设计建议,为新车型的MPDB碰撞安全性能设计提供参考。

E-NCAP proposes to use MPDB test in 2020. In order to study the impact characteristics under the new testing type, taking vehicle of different mass as the research object, and use simulation method for analysis of OLC, SD, bottoming out, etc. The research shows that the influence of small and large-size vehicles is great. Based on the analysis results, sums up some corresponding design suggestions, which can provide references for safety design of MPDB impact.
