doi:10.19562/j.chinasae.qcgc.2021.01.012

Abstract

Abstract:

In this paper， the test condition of crash with mobile progressive deformable barrier （MPDB） first defined in C?NCAP（2021） is presented， the evaluation indicators for crash compatibility are introduced and an optimization scheme of crash compatibility for MPDB crash condition is proposed. The results of simulation analysis and verification show that the optimization scheme can apparently enhance the score of crash compatibility with strong applicability.

Key words: C?NCAP, MPDB, crash compatibility
