Experiments were conducted on pulling head of human volunteers quasi-statically and influence which neck muscle activity responses have on neck bending characteristics was investigated. Experiments were conducted on impacting head of human volunteers and the human neck bending characteristics under different muscle conditions were quantified and analyzed. In this experiments especially, the head was modeled with a rigid body and the neck was modeled with beam, and the neck muscles were modeled with the springs, and the relation of the rotation angle and the moment of the Occipital Condyle joint were quantified as the neck bending characteristics.
