本研究的目的是发展一种具有梯度多孔四面体结构的假体设计方法,该方法将宏观层次上的连续体材料优化和微观层次上的多孔结构单元尺寸控制相结合。多孔假体的内部密度可随结构应力变化而变化,达到满足强度和刚度要求的最大孔隙率。与规则多孔结构相比,优化设计的假体可以具有更均匀的应力分布,假体的刚度更接近周围骨组织。
The purpose of this study was to develop a design method for prosthesis with gradient porous tetrahedral structure, which combines the material optimization of continuum body in the macro level and the element size control of porous structure in the micro level. The internal density of the porous prosthesis can change with the structural stress and achieve the maximum porosity satisfying the strength and stiffness requirements. Compared with the regular porous structure, the optimum design can have a more uniform stress distribution, and the stiffness of the prosthesis is closer to the surrounding bone tissue.
