摘要

摘要: 随着患有下肢运动障碍人数的日益增多,下肢康复逐渐成为多领域专家和学者的研究热点。为了能够研究不同足部轨迹对人体下肢主要肌肉疲劳程度的影响,首先设计了能够实现三种不同运动轨迹的机构,并采用SolidWorks进行三维建模;其次,根据特定身体参数在LifeMOD软件中建立对应的人体模型;然后在ADAMS动力学仿真软件中建立人-机耦合系统模型并实现该系统的运动仿真,得到特定人体按照不同足部轨迹运动时下肢主要肌肉伸缩量的变化情况。仿真结果表明:足部轨迹的不同对下肢肌肉伸缩量的影响较大,亦即对人体下肢肌肉疲劳程度的影响较大。因此,设计满足人体运动需求的具有合理运动轨迹的机构非常重要。

Abstract: As more and more people have lower limb dyskinesia, lower limb rehabilitation gradually receives greater attention from many scholars and researchers. In order to study the influence of different gait trajectories on the fatigue of the major muscles of a lower human limb, we design three mechanisms that can achieve different trajectories and use SolidWorks to build their three dimensional models. Then, we build the human limb model according to the model in LifeMOD. We use computer simulation to coordinate it with the three-dimensional models and obtain the results of change in stretch tensors of the major muscles. The simulation results show that different gait trajectories have different influences on stretch tensors, namely, fatigue. So it is very important to design mechanisms that have reasonable trajectories to meet the needs of human limb's movement. The analysis results not only provide the evidence for designing some mechanisms for lower human limb rehabilitation exercise, but also provide a new way of rehabilitation evaluation.
