摘要
阐述了股骨的自适应再造理论和自适应数值仿真方法。在对股骨的自适应仿真研究中,将股骨的材料看作是具有弹性的连续介质的正交各向异性特性,给出了股骨以应变能密度SED为反馈控制参数的带有死区的非线性的自适应再造数学模型。利用ANSYS平台提供的参数设计语言APDL编写程序实现了股骨再造自适应仿真,仿真结果与临床报道十分接近,说明了仿真数学模型的正确性。
The theory of femur adaptive remodeling and the method of femur adaptive numerical emulation are presented in this paper. Femur is a special material characterized by a continuous medium elastic and orthotropic body. The mathematical model of femur adaptive remodeling used SED（strain energy density）as a feed-back control variable and described non-linear remodeling process with dead zone. The procedure developed with APDL（ANSYS Parametric Design Language） in the ANSYS plane simulated the true process of femur adaptive remodeling. The result acquired by simulation was very similar to that from clinic report, which approved that the mathematical model was correct
