在人体外骨背架结构中引入弹簧阻尼系统,使背架结构与外骨骼髋部结构的连接具有更好的减震和缓冲作用。以PPS材料制作的背架结构为研究对象,60 kg为负重载荷,创新性地利用刚柔耦合方式对背架结构弹簧阻尼系统有限元模型进行处理,并进行人体支撑弯曲运动多载荷步分析,获得各工况应力值、变形量及分布图。经分析得,背架结构完全满足静力学各项性能参数要求。
The introduction of a spring damping system into the structure of the human body backbones makes the connection between the back frame structure and the hip structure of the exoskeleton better damping and buffering. PPS material made of the back-frame structure as the research object, 60 kg for the load, the innovative use of rigid-flexible coupling to the back frame of the spring damping system finite element model for processing and human body support bending movement multi-load step analysis, Get the stress values, deformation and distribution map of each condition. After analysis, back frame structure fully meet the statics of the performance parameters.
