Abstract The BioRIDII (Biofidelic Rear-Impact Dummy II) is regarded as possessing similar characteristics to human volunteers and PMHS (post-mortem human subjects) in terms of its response to low-speed rear-impact tests. The biofidelity of the RID 2 (Rear-Impact Dummy 2) does not yield satisfactory results in comparison to the BioRIDII. Although a great deal of research on the repeatability and reproducibility of the BioRIDII has been conducted, the research results to date do not directly suggest the neck injury criteria and limit values that should be set in safety regulations. The purpose of this research is to evaluate neck injury indicators for the BioRIDII using low-speed rear-impact sled tests on three sets of BioRIDII ver-g. A series of sled tests was conducted to assess the adequacy of neck injury indicators in terms of the repeatability and reproducibility of the results obtained for the three BioRIDII dummies tested. The sled tests were performed according to the test procedure proposed by K-NCAP (the Korea New Car Assessment Program). Several neck injury indicators, namely, NIC, Nkm, upper- and lower-neck Fx, upper- and lower-neck Fz and My, T1 X acc and Head X acc, were analyzed for each dummy. The results show that for some criteria, such as the lower-neck shear force and moment and T1 acceleration, the BioRIDII could be considered adequate.
