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