Abstract :
To develop a three-dimension finite element model of Chinese human neck for dynamic response. A 50th percentile adult human was chosen as a model, the 3-D FE model of C1-T1 was constructed by SCT scanning technology to get data of DICOM format, software Materialise mimics and Pro-E to achieve three-dimension reconstruction, software TrueGrid to mesh. The model was composed of cervical vertebrae, discs, facet joints, ligaments and muscles, which included 35042 nodes and 22618 elements. In LS-DYNA, the dynamic response of human neck under rear impact was investigated and compared with experimental results to validate the model. The method proposed could develop complex FE models with eight-node elements fleetly and accurately in order to make calculate more stably. The model may be used for further study on biomechanics.
