ISO 14879 膝关节试验：膝关节胫骨盘疲劳
膝关节胫骨盘疲劳性骨折是全膝关节置换（TKR）最常见报告的失效机理之一，它是由生物学反应，如磨损引起骨溶产生的骨丧失基本支持造成的。在这些条件下，胫骨盘的机械性能变得不稳定，正常步行给予的周期载荷引起疲劳裂缝，最终导致突变失效。
ISO 14879－1 标准“膝关节胫骨盘耐力测定“给出了一组通用的测试参数供测定和确认不同胫骨盘结构的疲劳特性。我们的8870电动机械测试系统和ElectroPuls™ 将在产品生命周期从获得基本材料性能，如抗疲劳裂纹扩展起，到测试整个胫骨盘的全过程为设计师、制造和研究人员提供帮助。
我们用试验夹具夹持胫骨盘的一半，模拟全支撑骨节，这样，未支撑的另一半骨节就承受典型的生理载荷，采用我们独特的动态载荷传感器可以消除动态惯性误差 （例如在环境浴槽中测试产生的由固定装置和流体力学因素引起的误差），能够更精确地测量施加于试样上的载荷。
我们建议您回顾一下ISO14879－1 以完全理解其要求。
