基于SolidWorks Simulation的人体踝骨力学分析

Mechanics Analysis of the Human Ankle Based on SolidWorks Simulation

建立一个基于SolidWorks Simulation的数字化研究平台,对正常人体足踝在外翻和内翻状况下进行有限元建模与分析。用CT扫描图像提取志愿者骨骼边缘轮廓数据,利用软件Mimics10.01进行图象三维重建,再将足踝各骨的点云文件导入到SolidWorks软件,利用网格处理向导及曲面生成向导建立三维实体模型,并在对模型进行内翻与外翻状态下,用SolidWorks中的插件Simulation对足踝部分发生形变的过程进行模拟分析。建立的足踝三维有限元模型具有较好的几何相似性,能够进行力学分析和测量,模拟分析结果经验证是可行的。基于SolidWorks Simulation的人体踝骨模拟力学分析是个有效可靠的方法,能提高对其力学机制的认识,并为临床相关疾患的诊治提供理论支持。

To establish a digital research platform based on SolidWorks Simulation, then model and analyze human being＇s ankle in conditions of valgus and varus. MimicslO.01 was used for geometric reconstruction of the ankle based on the CT data of the foot. The model was meshed and assigned with the material properties in SolidWorks software, then imported to simulation. And the distortion situation of the ankle was simulated and analyzed in conditions of valgus and varus. The three-dimensional finite element model of the ankle established had good geometric similarity and could do mechanics analysis and measurement. The simulating results were turned out to be feasible. The mechanics simulation analysis of the human ankle based on SolidWorks Simulation is a effective and reliable method. It can improve the understanding of the mechanics mechanism and provide theoretical support for the clinic diagnosis and treatment of related diseases.
