Study On Biomimetic Structure Of Upper Extremity Mechanical Bursa Of Exogenous

Now the exoskeleton mechanical arm has been widely used in rehabilitation engineering, This application not only gradually to meet the huge demand for the patients of physical therapy and rehabilitation treatment costs are lower, As exoskeletons rehabilitation devices in the clinical application and the analysis of the effect of rehabilitation, the problems existing in the mechanical recovery gradually performance significantly.Clinical application shows that drive mechanical arm exoskeletons human movement may cause permanent damage to the shoulder blade parts of the body, Significant symptom is pain in the shoulder. This article is on the basis of exoskeleton arm rehabilitation robot which can realize the basic action do structure designing for Scapular motion. Instead of electrical control with reliable mechanical transmission is the distinctive features of this study, With the need of power from the shoulder to the actuators, transmission path is complicated, and actuator position adjustment is required, so choose line pipe transmission power. Wire rope and the tube of teflon can be flexible to adapt to the position adjusted in space, Shoulder joint movement to achieve 2:1 rhythm, Actuator auxiliary scapula movement, improve the effectiveness of rehabilitation.The article expressed the auxiliary blade rotation system in detail design principle and design process. Using mechanical three-dimensional modeling design software completed the structure design and finite element software for the stress and deformation analysis of key components, and doing modal analysis test the model whether resonance excitation with source.
