摘　　要：以PPS材料制作的携行式外骨骼系统背架结构为研究对象,以60kg为承载负荷,对背架结构的无支撑弯曲、人体支撑弯曲、人体支撑侧摆三种工况进行有限元分析,并获得背架结构在各工况下的整体应力分布及特定路径下的应力和变形分布。经分析得知,在无支撑弯曲工况下背架结构将产生巨大的集中应力与变形,因此应尽量避免在该工况下进行运动。背架结构在人体支撑弯曲和侧摆工况下所得的应力分布和变形较为理想,背架结构完全能够满足在这两种工况下进行长期运动。A inting at finite element analysis for the portable exoskeleton＇s back shelf which is made by PPS and loaded 60kg payload to analyze the whole structure＇s stress distribution,the stress and defor- mation distribution under the specific path.The analysis is divided into three parts ,which are bending with no support,bending with human support and swaying with human support.According to the analysis results, bending with no support should be avoided, because it causes the large stress and distortion in back shelf. As to back shelf, stress distribution and distortion under swaying with human support is relatively ideal,so back long-term movement the condition of bending with human support and shelf can fully meet these two conditions under
