Abstract

The mechatronic ankle prosthesis plays a crucial role in the recreation of natural gait biomechanics by being able to actively control time-torque parameters in different sub-phases of the walking cycle. This paper presents a methodology for improving the design process of the individual characteristics of the object of interest. A series of tests were taken to derive a correlation between an actual structure and a developed mathematical model to determine the parameters of the object under investigation. The model provides a possibility to determine time-changing force-related properties to capture a full picture of the structure for which a particular design is being chosen. The method also acts as a tool to expand traditional design criteria to get the overall view of the structural dynamics of the mechanical system.
机电一体化假体动力学特性研究
机电踝关节假体能够主动控制行走周期不同子阶段的时间-扭矩参数,在重建自然步态生物力学方面起着至关重要的作用。本文提出了一种改进感兴趣对象个性特征设计过程的方法。进行了一系列测试,以推导出实际结构与开发的数学模型之间的相关性,以确定所研究对象的参数。该模型提供了一种可能性,可以确定随时间变化的力相关属性,从而获得所选择的特定设计的结构的全貌。该方法还作为一种工具,扩展了传统的设计准则,以获得机械系统结构动力学的整体视图。
