Abstract: An FE (finite element) neck model was improved with human like response in vehicle frontal, rear-end and side collisions based on an existing model developed in Hunan University. The model consists of the cervical vertebrae, intervertebral discs, ligaments and muscles that are modeled with various element types. The model was validated against kinematics data from volunteer tests carried out at the Naval Biodynamics Laboratory (NBDL) and Chalmers University of Technology. The results show that the model has good biofidelity with a good agreement with the test results for the main part of the time history of the collision events.
