D4a: Hybrid virtual dummy models (MADYMO neck-CHALMERS)

A 3 YOC neck FE model developed by ULP in RADIOSS platform was transfer to MADYMO platform and combined with Q3 dummy head model. The validity of the head-neck model was evaluated with the Q3 dummy head neck mini sled tests done at TUB in loading conditions for neck flexion, lateral bending and extension. The kinematics and calculated parameters from head-neck model were compared with measured acceleration of head CG, neck force and moment at OC joint in three directions.

A parametric study of 3YOC neck FE model was carried out for different input crash pulse levels, the resultant head CG acceleration and Nij criteria are used for analysis of the head and neck injury risk.

The 3YOC neck FE model is expected to be used for prediction of neck injury risks.
