Finite Element Analysis Optimises Material Selection and 3D Printing of Lower Limb Exoskeletons

Abstract

The purpose of the technology behind exoskeletons is to achieve human-machine motor function. The performance of the military, industry, and the medical field is all improved with exoskeletons. Rehabilitative benefits can be gained from using medical exoskeletons. The design and development of mechanical structures have an impact on the cost of metabolic processes, as well as size, portability, and cost. Exoskeletons are now within reach of consumers in underdeveloped nations thanks to the miniaturisation of components including electronics, controls, motors, and drives. The use of alternative material for the exoskeleton structure improves both its safety and its strength while simultaneously reducing its overall cost. Frames can be made out of metals, composites, or polymers. In this study, the technology of additive manufacturing is used to choose the components that will go into an exoskeleton frame for lower limb rehabilitation. CATIA v5 generates a 3D model, and Ansys carries out a finite element analysis to estimate the deformation of the material and determine whether or not it is appropriate for use by various age groups.
