人工关节不稳定仍然是翻修手术的最常见原因之一，其原因是多种因素造成的。为了调查不稳定的机制，如在可再现的，生理上现实的边界条件下的位错，一种新的测试方法是通过一个硬件在环（HiL）仿真，涉及一个高度灵活的机电一体化测试系统。在这项工作中，基本的概念和实施的所有必需的单位，使不同的全髋关节和膝关节置换术，分别进行比较调查。HiL关节模拟器由两个单元组成：由六轴工业机器人组成的物理设置和实时运行的数值多体模型。在多体模型内，所考虑的关节的解剖环境被表示为使得在不稳定事件期间考虑软组织反应。因此，机器人根据由多体模型提供的信息装载和移动真实的植入物部件，同时将记录的位置和阻力矩传送回。通过测试基本控制原理证明了模拟器的功能，并通过再现标准全髋关节置换术的脱位过程进行了验证。HiL模拟提供了一种新的生物力学测试工具，用于分析不同关节置换系统在真实运动和生理负载条件下的不稳定行为。
Instability of artificial joints is still one of the most prevalent reasons for revision surgery caused by various influencing factors. In order to investigate instability mechanisms such as dislocation under reproducible, physiologically realistic boundary conditions, a novel test approach is introduced by means of a hardware-in-the-loop (HiL) simulation involving a highly flexible mechatronic test system. In this work, the underlying concept and implementation of all required units is presented enabling comparable investigations of different total hip and knee replacements, respectively. The HiL joint simulator consists of two units: a physical setup composed of a six-axes industrial robot and a numerical multibody model running in real-time. Within the multibody model, the anatomical environment of the considered joint is represented such that the soft tissue response is accounted for during an instability event. Hence, the robot loads and moves the real implant components according to the information provided by the multibody model while transferring back the position and resisting moment recorded. Functionality of the simulator is proved by testing the underlying control principles, and verified by reproducing the dislocation process of a standard total hip replacement. HiL simulations provide a new biomechanical testing tool for analyzing different joint replacement systems with respect to their instability behavior under realistic movements and physiological load conditions.
