Abstract	A human FE model for rear-end accident analyses was developed in order to reconstruct not only the whole body motion but also vertebra motions during impact. The validation of the human FE model was confirmed as follows; The original model was validated against data obtained from human volunteer testing during low-speed rear-end impacts in the past. This model was further validated by PMHS at a high speed. This comparison showed that the human FE model could reconstruct the whole body and cervical vertebral motions of the PMHS. Furthermore rear-end accident reconstruction simulations were conducted with the human FE model. The simulations correlated the strains of the inter-vertebral discs and the facet joint capsules, with that of the neck injury severity recorded in the accident data.
