Dynamic Characteristics of the Skull with the Neck Effect

The human head is a combination of the variety of different tissues of the skull, brain, cerebellar, brainstem, cerebrospinal fluid (CSF), and neck bone, etc. The differences of both skull and neck bone combined reaction and pure skull reaction are discussed in the analysis. Finite element method (FEM) is employed not only to analyze the natural vibration modes but also to understand the reaction of the combinations of the skull and neck bone. To evaluate the realistic dynamic behavior of the human head, white light scanner and 3D graphics software are used to construct the skull and neck bone combined model. After confirming the correctness of the skull and neck bone combined model and pure skull model, respectively, the real human bone properties are brought into models and the comparisons about the simulated normal modes analysis of the two models are obtained. The found natural frequencies of the human skull-neck structure will help to avoid the injuries on head or neck. [B.W. Huang, Y.-W. Ou, C.H. Chang, et al.
