Abstract

Validated criteria are vital tools in crash-safety research and development. In this study, NIC max outcomes from mathematical simulations were compared with real-life data in terms of the risk of sustaining long-term soft-tissue neck injuries in rear-end impacts. Mathematical models of the BioRID I and car seats were exposed to a broad set of low-speed crash pulses. It was found that the two seats representing cars with high neck-disability risk in real-life impacts resulted in higher NIC max values compared to the two low-risk seats. The mathematical simulations were also used to evaluate the influence of crash-pulse parameters on NIC max. It was found that the commonly used change of velocity, j v, was not a good predictor for NIC max , nor was the crash-pulse peak acceleration. The change of velocity during the first 85 ms of the impact, j v 85 ms , correlated with the NIC max and has therefore the potential to quantify impact severity. Furthermore, impacts with crash-pulse-recorder equipped cars, reported by Krafft et al. (2000), were reconstructed.
