Modal analysis of the human head-neck mathematical model

摘要：

　　In this paper, the modal responses of the finite element (FE) model of human head-neck under vibration have been simulated.These modal responses are found to be in reasonably good agreement with previous studies.Additional and rarely reported modal responses such asmastication modes of the mandible and flipping of nasal lateral cartilages are identified.Modal validation in terms of modal shapes suggests a need for detailed modeling to identify all the additional frequencies of each individual part.It is found that damping has a trade-off effect in reducing the resonant frequencies in lowering the peak biomechanical responses as well as in the higher frequency modes.Although the finding suggests an optimized estimate of damping factor of O.2 for both modal and dynamics responses, there is still a need for further study in determining an appropriate damping factor.
