Abstract: 建立一体化小腿假肢和残肢的三维模型 ,应用有限元分析方法 ,计算此模型在模拟 Mid- Stance步态时相的载荷作用下各节点的应力 ,从而得到此模型内外表面的应力分布 ,为一体化假肢设计的 CAD\CAM系统提供理论依据。计算结果表明 ,接受腔的应力值较小 ,假腿的应力值较大 ,高应力区出现在假腿下端及接受腔与假腿的交界区域。
In this study, a 3D model of a transtibial monolimb and residual limb was constructed. The stresses on all nodes of the model under the simulus of the load at the Mid-Stance were computed through 3D finite element analysis (FEA). The stress distribution on the internal and external surfaces of the model was obtained. The results indicate that the stresses on socket are lower than those on prosthetic shank; high stress regions are located on the underneath of prosthetic shank and the border section of socket and prosthetic shank. These data will be useful for CAD\CAM system of monolimb designing.
