摘要
MPDB(移动渐进变形壁障)碰撞试验是兼容性考察工况,E-NCAP及C-NCAP将分别在2020年及2021年引入该工况取代ODB(可变形壁障)碰撞试验,由于工况更新,壁障由原来的ODB壁障改为MPDB壁障。2种壁障完全不同,文章对2种壁障进行了对比,分别建立动静态压溃模型,得到了壁障在不同载荷下的响应曲线,对壁障的比较研究可以为后续车型开发提供参考和指导。
The MPDB(moving progressive deformable barrier)crash test is a compatibility inspection condition.E-NCAP and C-NCAP will use MPDB crash test to replace ODB test in 2020 and 2021 respectively.Due to the updating of the working conditions,the barrier will be changed from the original ODB to MPDB.The two kinds of barriers are completely different.This paper compares the two kinds of barriers,establishes the dynamic and static crushing models respectively,and obtains the response curves of barriers under different loads.The comparative study of the barriers can provide reference and guidance for the subsequent vehicle development.
