| Summary: | 碩士 === 國立成功大學 === 土木工程學系碩博士班 === 94 === Nowadays, biomechanics has made a significant breakthrough under the enhancement of increasing speed of computers, coupled with use of powerful finite element software. In current literatures, there are few articles about the topic of a whole lumbar spine model (L1~L5), this study builds a finite element model of the whole lumbar spine and makes basic research on biomechanics.
This study first obtained a 3D surface model of whole lumbar spine (L1~L5) through use of medical image processing program 3D-DOCTOR, based on the slices from scanning of the practice specimen of lumbar spine. With the preprocessing program MSC.PATRAN, and inclusion of both essential and natural boundary conditions, loading condition causing from the contact effect of facet joints, a final finite element model built to submit to analysis code ABAQUS.
The basic biomechanical analysis of this study was composed of three simulations with five motion behavior including flexion, extension, left and right lateral bending and axial torsion, and with each case under the considerations of different material properties of fiber tissue, contacting frictional property of facet joints and effect of ligaments.
