| 摘 要： | 椎间盘在脊柱运动中起着重要的作用,根据椎间盘的生物力学特点建立力学模型.采用复合材料力学中的弹性嵌入体解,建立了椎间盘的一个横观各向同性圆柱体力学模型.求出了腰椎间盘在直立位、弯曲及扭转作用下的应力应变和位移解.得出结论椎间盘在受复合载荷的作用下更易被破坏.

| Abstract: | Objective： The intervertebral disc plays the essential role in the motion of spine kinematics.According to the biomechanics characteristics of intervertebral disc,the paper established its mechanical model.Method： It used the elastic inserting solution in the mechanics of composite materials,and established a transverse isotropic column mechanical model of intervertebral disc.Result： It sought the stress,strain and displacement of intervertebral disc when the lumbar spine was upright,bending and torsional.Conclusion： The intervertebral disc is easier to be damaged under the complex loads. |
