摘要

本研究深入探讨了人工踝关节制造中常用的各种材料的生物力学特性。具体来说,本研究侧重于设计一个类似于 salto-talaris 型的踝关节,旨在全面了解其在不同负载条件下的性能。本研究采用先进的有限元分析技术,对所设计的踝关节在承受不同载荷时的应力和位移进行了严格评估。此外,这项研究还致力于确定与这些位移相关的振动频率,为了解踝关节的动态行为提供宝贵的见解。值得注意的是,分析扩展到研究三个运动轴的随机频率,从而能够全面评估关节功能过程中可能出现的定向变形。为了验证拟议设计的有效性,我们将踝关节设计与星形踝关节设计进行了对比分析,星形踝关节设计是公认的踝关节假体基准。这种对比方法有两个目的:确认从 salto-talaris 设计中得出的结论的准确性,以及阐明所建议的设计在实际应用场景中的相对有效性。

Investigating Material Performance in Artificial Ankle Joints: A Biomechanical Study
This study delves into an in-depth examination of the biomechanical characteristics of various materials commonly utilized in the fabrication of artificial ankle joints. Specifically, this research focuses on the design of an ankle joint resembling the salto-talaris type, aiming to comprehensively understand its performance under different loading conditions. Employing advanced finite element analysis techniques, this investigation rigorously evaluates the stresses and displacements experienced by the designed ankle joint when subjected to varying loads. Furthermore, this study endeavors to identify the vibrating frequencies associated with these displacements, offering valuable insights into the dynamic behavior of the ankle joint. Notably, the analysis extends to studying random frequencies across three axes of motion, enabling a comprehensive assessment of directional deformities that may arise during joint function. To validate the effectiveness of the proposed design, a comparative analysis is conducted against the star ankle design, a widely recognized benchmark in ankle joint prosthetics. This comparative approach serves dual purposes: confirming the accuracy of the findings derived from the salto-talaris design and elucidating the relative efficacy of the proposed design in practical application scenarios.
