| 摘 要： | 作为一种活性生物器官 ,骨骼不同部分的密度在给定荷载下要发生变化 ,这种现象叫骨重建。定量的研究骨重建现象是骨生物力学的重要组成部分。在 Cater所做的骨材料的实验基础上 ,骨骼的不同微小部分被简化当作一种各向同性材料。再以有限元分析和迭代计算为手段 ,可以获得一种定量计算骨量的方法。与实验结果对照可以发现 ,此方法可使问题得到解决。

| Abstract: | As a kind of active system of creatures, the apparent density of different part of bone is changed under applied loads, which is called adaptive remodeling. The research of quantitative analysis of bone remodeling is an important part of bone biomechanics. Based on the experiment of bone materials done by Cater, bone was defined as a kind of isotropic material in every small part of bone. Then the simplification model of bone material will be got. And using the finite element analysis and iterative method, the apparent density of bone can be calculated quantitatively. Compared with data got in experiment, the method can solve the problem quickly and successfully. |
