| 摘 要： | 本研究选择一位32岁正常男性,用CT扫描的方法,借助CATIAV5和MSC.Marc/MSC.Mentat软件,建立正常人L3-L5的三维非线性有限元模型。计算了模型在10N·m纯力矩作用下脊柱功能单位的平均刚度,参照前人尸体标本生物力学测试结果,验证了模型的有效性。本模型可用于进一步的临床生物力学研究。

| Abstract: | In this study, a detailed L3-L5, three dimensional nonlinear finite element model of a normal aged 32 man was established with the aid of two softwares, CATIAV5 and MSC. Marc, which can derive a three-dimensional finite element model from CT images. We loaded the model with 10 N * m net moment and computed the average rigidity of functional spinal unit. The model was validated in contrast to the former biomechanical studies of cadaveric spine. The model will be used in further clinical biomechanical studies. |
