Research and Analysis on Airbag Dangerous Deployment Evaluation Based on 2024 Version C-NCAP

Research on the subjective items of airbag dangerous deployment in the 2024 version of C-NCAP regulations, which includes two aspects: the action of the airbag sweeping over the face and the speed of airbag deployment. This article starts from other aspects. On the one hand, when examining the action of airbags sweeping over the face, it is necessary to consider the acceleration index. Based on the head injury index of the front dummy in collision in C-NCAP, the injury index of face - sweeping risk is defined; On the other hand, the force level of facial injury should also be examined, and the definition and experimental methods should be discussed based on the force level that the head can withstand. Added airbag deployment hazard assessment for the HIII 5 female dummy.
