Finite Element Analysis And Design Of Wearable Lower Extremity Exoskeleton

Contents of this paper is wearable robotic exoskeleton lower extremity rehabilitation, access to domestic and foreign research data, we can learn that the current drawn widespread lower extremity rehabilitation exoskeleton structure bulky, single rehabilitation, not widely applicable issues. Using three-dimensional motion capture system of normal human lower extremity motion data collection, analysis of lower limb movement mechanism, based on ergonomics, combined with man-machine system design requirements, using bionic anthropomorphic mechanical design principles and modern design methods, design a lightweight structure, with full rehabilitation orientation function is widely used for lower limb rehabilitation wearable exoskeleton robot is essential.Lower extremity exoskeleton for structural design, this paper is use of SolidWorks software to draw a three-dimensional solid model of the exoskeleton parts, and virtual assembly; using ANSYS software for static lower extremity exoskeleton characteristic analysis, analysis of stiffness and strength exoskeleton design meets requirements; foreign bones modal analysis, the exoskeleton of natural frequencies and mode type proposed base changes in the natural frequencies and mode shapes of damage identification method to identify the external damage bones, lay a theoretical foundation for the exoskeleton safety testing, maintenance equipment.
