Optimization And Simulation Of Dynamic Lower Limb Walking Aid

Dynamic lower limb walking aid is a kind of robot which combines itself with human body to help people walk.It can be used as a walking tool for paraplegic patients or as an instrument for rehabilitation training of stroke patients in the field of rehabilitation medicine.With the development of related technology,dynamic lower limb walking aid help more and more patients with lower extremity disability to recover walking function,which has become a hot research topic.The dynamic lower limb walking aid for rehabilitation training of patients with lower extremity disability caused by stroke disease was studied.The power of the domestic and foreign lower limb walking aid products were introduced.And the product problems were summed up.Combined with the lower limb of the human body.Vicon system was used to collect and analyze the gait data of normal human body.This article made to work on the basis of the above.(1)The structure and existing problems of TUST-3 type dynamic lower limb walking aid are analyzed.(2)The structure of TUST-3 type dynamic lower limb walking aid was optimized and the power module was re-selected.(3)The three-dimensional modeling of dynamic lower limb walking aid is built.The model is simplified and the overall statics analysis is carried out.The results meet the requirements of the mechanical properties of the selected materials.(4)The simulation results show that human wearing walking aid can walk according to human gait The selected driving device can meet the power demand of normal walking of the walking aid of the human body.The relation between the stroke of the ball screw and the rotation angle of the joint is determined,and the theoretical basis is provided for the debugging of the prototype.(5)The prototype of dynamic lower limb walking aid is made and debugged.A walking test was carried out with a dynamic lower limb walking aid.The results show that the walking aids can basically follow the gait of normal people.
