摘要: 针对具有下肢运动障碍的偏瘫及脑卒中患者,提出一类基于并联机构的下肢康复机构,此类机构具有三平移的运动自由度,其结构关于单一平面对称。康复训练机构基于站姿康复,通过动平台带动踝关节的运动完成人体下肢康复训练,使康复训练形式多样化,康复过程中患者能够获得一定的适应性以及舒适性。基于螺旋理论型综合方法给出四种分支自由度为4的基础构型,择优选取了一种分支结构为PRPR的并联机构作为康复执行机构;对该机构进行了运动学分析,求取了机构的工作空间;基于不同的康复形式进行了轨迹规划;通过冠状面和矢状面的角度实验验证了机构具有运动不受平面限制的性能。

Abstract: Aiming at hemiplegia and stroke patients with lower extremity dyskinesia, a type of lower extremity rehabilitation mechanism based on parallel mechanism is proposed. This kind of mechanism has three translational degrees of freedom, and its structure is symmetrical about a single plane. Rehabilitation agency based rehabilitation stance, driven by the movement of the ankle joint moving platform to complete the human lower limb rehabilitation training, diversification of forms of rehabilitation, the rehabilitation process of patients able to obtain a certain flexibility and comfort. Based on the spiral theory type synthesis method, four basic configurations with 4 branch degrees of freedom are given, and a parallel mechanism with a branch structure of PRPR is selected as the rehabilitation actuator; the kinematics analysis of the mechanism is carried out, and the mechanism is obtained. workspace; trajectory planning was based on different forms of rehabilitation; the angle coronal and sagittal experimental verification mechanism having a performance of the motion plane is not limited.

Key words: lower limb rehabilitation, parallel mechanism, triple translation, mechanism synthesis
