In this paper, we present a three-dimensional mathematical model for a normal hip joint. The three-dimensional finite element model has been constructed based on Computer Tomograph scans of the bones. The obtained 3D model is studied using the finite element method, taking into consideration the real structure of the bone and the mechanical characteristics of cortical and spongy. The FE model of hip joint, the material properties used to simulate the behavior of the cortical and trabecular bone (of femur and coxal bone) and the cartilage, as well as the boundary conditions are presented. The distribution map of the axial and global movements on the global model and the distribution map of the axial and von Misses strain in the cartilaginous surface of the femur are presented.
在本文中,我们提出了一个正常髋关节的三维数学模型。该三维有限元模型是基于骨骼的计算机断层扫描构建的。利用有限元方法对所得的三维模型进行研究,同时考虑了骨骼的实际结构以及皮质骨和松质骨的力学特性。文中给出了髋关节的有限元模型、用于模拟股骨和髋骨的皮质骨与小梁骨以及软骨行为的材料属性,以及边界条件。展示了全局模型上轴向和整体运动的分布图,以及股骨软骨表面轴向和冯·米塞斯应变的分布图。
