Structure Research on Carrying Frame in Portable Exoskeleton Make by Polyphenylene Sulfide
As carrying frame make by Polyphenylene Sulfide in Portable Exoskeleton to the research object, establish the 3D model of carrying frame on the basis of the configuration parameters of Human body backside, and implement the strength and stiffness analysis through the ANSYS software. The analysis is divided into three portions in accordance with working conditions, bending with no support, bending with human support and swaying with human support. Thereinto three portions have the same payload as 45 kg and the same bending range attains 45 degree. Ultimately Stress value, quantity and distribution chart of the deformation have been obtained for each portion. Analysis results show that the each direction deformation Maximum and the stress Maximum of the carrying frame which bend without support present linear growth along with the increase of the bending angle in the course of the bending over. Therefore it causes the larger concentration of stress and deformation in the carrying frame and causes the additional load in the body. So the working conditions for carrying frame should be avoided which bend without support. To the rest of the two conditions, the stress and deformation of carrying frame are small enough to be meeting the use requirements.
