| Popis: | This paper analyzes the flexion and extension of three joints of a single exoskeleton mechanical finger. According to the motion characteristics of the finger, a finger rehabilitation exoskeleton robot is designed to assist patients with hand function for rehabilitation training. The three-dimensional model was established by SolidWorks, and the initial state of the robot was set under the action of gravity. The finite element analysis method was used to analyze the stress of the key components, including calculate and analyze its stress and strain. The simulation showed that the maximum stress of key components in rehabilitation training was 2140 (Pa), which is far less than the yield strength of the material 60 (MPa), and the maximum deformation was 0.092 (mm). The simulation result revealed that our design did not lead to failure of mechanical structure, which would provide a certain reference basis for its structural optimization design. |
