Abstract [en]

Neck injury due to low severity vehicle crashes is of worldwide concern and the injury risk is greater for females than males. However, whiplash protection systems have shown to be more beneficial for males than females. Hence there is a need for improved tools to address female protection. The objective is to develop and evaluate a 50th percentile female rear impact crash dummy FE model. The model was based on the same design concept as the BioRID II. A scaling approach was developed and the first version, EvaRID V1.0, was implemented. Its dynamic response was compared to rear impact tests with female volunteers. The EvaRID model and volunteer tests showed good correlations until 250 ms of the head and T1 accelerations, linear displacements and head angular displacement. Considerably less T1 angular displacement was found for the EvaRID; similar results were obtained for the BioRID II. Thus, the EvaRID V1.0 and BioRID II models have limitations at low ÎŽv (7km/h). The EvaRID model demonstrated the potential to become a valuable tool when evaluating and developing seats/whiplash protection systems, however, this will require updating the joint stiffness. The model may be used as a template for the development of a physical female dummy.
