摘要：

背景：课题组前期实验已建立了数字人体多个部位的骨骼有限元力学模型，但如何能在保证模型收敛的情况下提高模型精度与有效性，有待进一步研究。
目的：建立精确的数字力学人颈椎运动节段模型。
方法：采用中国数字人男1号数据，使用经Materialise 公司授权试用的MIMICS13.1医学图像重建软件进行三维有限元建模，其结果导入ABAQUS6.7有限元系统进行处理，观察试运行结果，对模型的有效性进行验证。
结果与结论：在大型有限元软件ABAQUS6.7中调用颈椎运动节段三维模型的“.lis”文件，获得颈椎运动节段的有限元模型，此模型共有节点10 465个，单元52 752个，模型经验证有效。结果证实，实验成功建立了高度拟真的数字力学人颈椎运动节段有限元模型。

Abstract:

BACKGROUND: Our team has built finite element dynamic bone models of different parts, but how to ensure the model’s precision and effectiveness, there still needs further study.
OBJECTIVE: To provide accurate biomechanics model of Digital Human.
METHODS: The CT data of Virtual Chinese Human --the male No.1 (VCH-M1) were imported into the MIMICS13.1 software authorized by the Materialise Company, and then the outcome document was entered into the ABAQUS6.7 software to perform finite element analysis. The result was observed and then the effectiveness of the models was tested. 
RESULTS AND CONCLUSION: The “.lis” document was chosen in the finite element analysis software ABAQUS6.7. Three dimension models of cervicalt were acquired. The model has 10 465 panel points and 52 752 units. It is verified that this model is effective. Results confirmed that the biomechanics model of Digital Human can be calculated for meeting the revolutionary requirement of the future digital medical science.
