碩士 === 國立成功大學 === 土木工程學系碩博士班 === 96 === Because of the modern technology computers are devised, many studies of biomechanical are improved by finite element method. The computers will save us a lot of time to get the analytic results. In this dissertation we create the vertebrate model by finite element method and discuss all FSU by simple biomechanical. First we use CT to scan all vertebrate, then improve the DICOM.file to 3D-Doctor, finally improve the STL.file to MSC.PATRAN. After all the processes we set materials, properties, boundary conditions. This study uses the notable finite element method to simulate the human spine from cervical to lumbar (C2~L5). This finite element model adopts the distinct semiautomatic modeling method to build the truly accurate geometrical human spine from CT scan (not including the ribs and cervical) and contains the facets contact interactions and the programmable nonlinear ligaments. The numerical results are confirmed by the validation and convergence test. In the conclusion, the feasibility of analyzing the entire spine could be verified by this study.
