摘要

目的：建立髋关节三维有限元模型，并验证其有效性，以用于后续的生物力学分析。方法：选取1名志愿者，采集髋部CT数据，导入软件Mimics 14.0软件，建立髋三维几何模型，再经Ansys13.0软件划分网格、赋材质，建立三维有限元模型。在此模型上施加220N髋关节正立位的模拟体重压力，其应力分布与相关文献对照。结果：成功建立了髋关节三维模型和有限元模型，节点数为284 183个、单元数为160 665个。在模拟重力作用下，应力分布与之前的实验结果一致。结论：建立的三维有限元模型其有良好的仿真性，可以用于临床生物力学分析。

Abstract

Objective: To establish a 3D finite element model of human hip joint and verify its validity, to be used for subsequent biomechanical analysis. Method: The hip joint in one healthy adult male volunteer was scanned by CT. The 3D finite element model of the hip joint was constructed with Mimics and Ansys software. The simulated weight pressure of hip upright position was applied to this model, the stress distribution was compared with the related literature. Result: The 3D finite element model of human hip joint was established successfully, including 284 183 points of 160 665 units. Under the action of simulated gravity, the stress distribution was in agreement with previous experimental results. Conclusion: The established 3D finite element model had good simulation and could be used in the clinical biomechanics analysis.
