Research On The Optimal Design Of The Fusion Of The Shape And Structure Of The Lower Extremity Rehabilitation Exoskeleton

Stroke patients and those with limb dysfunction caused by accidents need long-term rehabilitation training.The traditional manual-assisted rehabilitation training method is time-consuming,labor-intensive,and costly.It cannot solve the outstanding problems of current aging services and rehabilitation needs.Therefore,rehabilitation exoskeleton device has become a current research hotspot.For a long time,the research on rehabilitation exoskeleton has mainly focused on its mechanical structure,control algorithms and ergonomics,while neglecting the research on the modeling and lightweight of lower extremity rehabilitation exoskeleton,which has caused many existing exoskeletons Problems such as dull shape and bulky structure.The rigid shape can't make patients interested in the use of rehabilitation exoskeleton,and the bulky structure will increase the difficulty of control,energy consumption and cost on the one hand,and on the other hand,there will be greater hidden safety risks.Aiming at the current research status,this paper proposes a comprehensive design method that complements the styling design and structural optimization,and optimizes the design of the lower extremity rehabilitation exoskeleton,so that the designed lower extremity rehabilitation exoskeleton meets the dual requirements of beautiful appearance and lightweight structure.Claim.First,according to the functional structure requirements of the lower extremity rehabilitation exoskeleton,the structural configuration of the lower extremity rehabilitation exoskeleton is obtained,and the components that can be optimized are found;then,the general characteristics of the lower extremity rehabilitation exoskeleton design are summarized by using the sensibility engineering theory and design aesthetic principles,And combined with the structural configuration in the design of the lower extremity rehabilitation exoskeleton,and then use the 7-point scale of the semantic difference scale to select the modeling plan.Secondly,in order to verify the rationality of the modeling scheme structure,SolidWorks software is used to perform three-dimensional solid modeling on the preferred scheme and perform finite element analysis to verify whether the designed modeling scheme structure is reliable;On the basis of,use topological optimization method to carry out lightweight design.The final design of the styling scheme is outstanding in terms of styling aesthetics and structural performance,indicating the effectiveness of the comprehensive design method and providing reference for the development and design of relevant designers.
