Crash pulse characteristics and seat type are the causative factors for the whiplash risk of an occupant in rear impacts. In this study, a 50th percentile male human-body model sitting in a typical rear seat is subjected to 28 crash pulses with varying severities and pulse shapes. Delta-V, peak acceleration and peak moving average acceleration of these crash pulses are documented and investigated. During the simulations, both the upper and lower neck forces/moments are recorded according to the EuroNCAP and the China NCAP dynamic whiplash test protocols. Both linear and bilinear regression analyses have been performed to find correlations between crash pulse characteristics and neck loading. The peak acceleration of the crash pulse is not found influential. The peak moving average acceleration and delta-V correlate with neck loading. It is found that peak moving average acceleration has a higher share of influence on neck loading compared to delta-V. In bilinear regression models involving both delta-V and peak moving average acceleration as input variables, coefficient of determination values reach as high as 0.93. It is observed that the shape of the crash pulse is also an influential factor determining injury risk.
