Translated Abstract
China is one of the places with high incidence of chronic diseases and strokes, in every year a large percentage of stroke patients suffer sudden incidents which cause dysfunction in their bodies due to which they face severe problems in society to adequately sustain in life-balance. The damages caused by chronic diseases and strokes are very likely to hinder the normal functioning of hand functions, significantly limit people＇s daily activities and reduce people＇s quality of life. To treat patients safely, autonomously, and conveniently, reduce the cost of rehabilitation treatment, and improve the quality of life of patients, we designed and manufactured a flexible finger rehabilitation exoskeleton for actuating and measured its performance parameters.
This paper compares the rigid flexible rehabilitation exoskeleton robot and various driving methods. In order to ensure the stability of the structure and output force and improve the comfort and portability of the robot, this paper chooses to design a flexible pneumatic type of finger rehabilitation exoskeleton robot driving actuator.
This paper analyzes the influence of different structures on the expansion characteristics of pneumatic actuators and the influence of the number and distribution of pneumatic units on the performance of rehabilitation hand-actuated actuators. Combining the hand features with the biological characteristics of the hand and the characteristics of stroke patients with stroke dysfunction. This paper produced a driving actuator through 3D printing technology.The objective of this is paper is about designing the 3D structure of actuator that can be easily 3D printed and can be easily installed with pneumatic actuating control system. The design of actuator was modified several times in order to get improved and optimized structure while inserting the air pressure considering pneumatic actuation parameters and the simulation of actuator along with the mechanical properties of the material using SolidWorks and Abaqus respectively.
While the flexion bending of 3D printed actuator is performed in practical experiment, in which we obtained the results of the flexion angles of finger-actuator with timely applied pressure. The readings of applied force on tip of actuators were measured to gain the accurate and feasible result.The results show that the driving actuator can better realize the function of driving the patient＇s finger flexion, satisfying Design requirements.
