Abstract

Abstract: In order to improve the physical and mental health of the elderly and disabled people and reduce the burden of the family,it designs a two-phase travelling rehabilitation exoskeleton based on TRIZ,which is able to achieve the main functions of walking rehabilitation training and wheelchair travelling. The TRIZ innovation tool is used to solve the exoskeleton sit-to-stand conversion problem,and the exoskeleton prototype is statically analysed under load by ANSYS software. In order to explore the performance of the exoskeleton in the dynamic environment,kinematics and dynamics modelling of the exoskeleton is carried out,and a virtual prototype model is built and imported into ADAMS software for motion simulation,which verifies the feasibility of the design scheme through the analysis of the simulation data and provides a theoretical basis for the next step in the production of physical prototypes.

Key words: two-phase traveling, rehabilitation exoskeleton, structural design, simulation analysis
