基于Solidworks的个体化人工膝关节设计及有限元分析

Design of Individualized Artificial Knee Joints and Analysis of Finite Element Based on Solidworks

通过CT影像数据、Mimics软件和逆向工程软件Imageware实现患者膝关节软骨面的个体化三维重建,然后在Solidworks软件中对该重建的三维模型进行计算机辅助设计,最后将设计的实体模型导入到有限元分析软件ANSYS中进行Von Mises应力分析,以分析和评价设计的合理性。

Through CT image data,Mimics software and reverse engineering software Imageware,the individualized 3D model reconstruction of the patient＇s knee joint cartilage surface is achieved. Then the reconstructed 3D model in Solidworks software is made by CAD. Finally,Von Mises stress analysis is given by importing the designed solid model into finite element analysis software ANSYS,so as to analyze and evaluate the rationality of the design.
