碩士 === 正修科技大學 === 機電工程研究所 === 104 === In this study, the computer-aided design software SolidWorks is employed to model the structure of human head, such as the skull, neck bones, brain stem, brain tissue and cerebrospinal fluid (CSF). The finite element analysis software ANSYS Workbench is also used to study the dynamic properties for system. To make the correct results, the human physical material properties of density, Young's modulus, Poisson ratio and other parameters are considered in this work. Dynamic analysis such as natural frequency, modal analysis and impact response are focused. Finally, the impact effect on head injury criterion (HIC) is also considered to study. The analysis results can be employed to provide the dynamics, impact response and head injury criterion useful data for human head research.
