Finite Element Analysis and Optimization of Power-Assisted Structure of Wearable Human Lower Limb Exoskeleton

In this study, a multi-shape object-oriented human motion model is built using HumanCAD simulation platform to simulate the movement of a particular action; taking structural load-bearing characteristics as the objective function, combined with ergonomic parameters of the constraints, using particle swarm optimization, the study has made an optimized simulation of lower limb three-hinge power-assisted structure for multi-object under multiple constraints and established solid models with Solidworks based on the optimization; the study has realized data exchange between the analysis software of Ansys and the solid models, built a multi-rod coupling analysis model, made the strength calculation and modal analysis, proposed optimization strategies to make improvement, and provided parameters for structural dynamics optimization design.
