摘要
采用了一种非线性骨再造速率方程与有限元法相结合，引入工程拓扑优化思想，讨论了初始形状、有限元网格细化对模拟得到的人椎体外形、内部结构和质量的影响。
The purpose of this paper is to discuss the application of topology optimization in the simulation of bone's structure. A nonlinear speed equation of bone's reconstruction combining with the finite element method (FEM) is adopted. By introducing topology-optimizing concept into engineering, the influences of original shape and refining of FEM meshes are discussed on the shape, inner structure and mass of human vertebra.
