摘要:
介绍一种新型无创可延长假体的延长结构,并对延长结构做应力分析和优化。利用三维设计软件PRO/E(PTC公司,美国)建立具有不同规格延长结构的三维模型;通过有限元方法分析得出优化的延长结构,并用物理实验验证。研究表明,延长结构的最大负载能力主要取决于聚缩醛(polyoxymethylene,POM)材料制成的限动管,仿真与物理实验结果所呈现的不同规格延长结构的静态力变化趋势基本一致;对于本研究的多种延长结构来说,移动管凸起的外径φ为19 mm、凸起角度γ为15°至45°之间最佳。因此,本研究提出的延长结构设计原则以及分析与验证结果,为新型无创可延长假体深入研究奠定了良好的理论基础。
Abstract:
To design a new extension structure of the noninvasive extendable prosthesis,to analyze and optimize the stress of the extension structure. The three-dimensional model of the different specifications extension structure was established by using the Pro/Engineer software (PTC, USA). The optimal extension structure was obtained by finite element method analysis and physical experiment verification. This study showed that the maximum load capacity of the extended structure depended on the control tube made of POM (Polyoxymethylene). The simulation and physical experiment results revealed that the static force change trend of the different specifications extension structure was similar. The diameter (φ) of mobile tube bulge was 19 mm and the convex angle(γ) between 15 ° and 45 ° was best for a variety of extension structure. Therefore, the extension structure design,analysis and verification results of this study have laid a good theoretical foundation for the new noninvasive extension prosthesis.
