摘要现阶段我国人口老龄化日益严重，有下肢运动障碍的患者数量逐年增多，而国内下肢康复医疗设备研究技术还不成熟，特别是站立式下肢康复设备研究甚少，站立式动态康复设备亟待开发。针对此需求，本论文提出了一种新型电动步行训练器的设计方案，包括机械系统的设计和控制系统的设计。并设计了训练器的整体机械结构、运动驱动机构、减重装置高度调节机构、减重装置拉绳机构。同时，基于AVR单片机ATmega8搭建步进电机的控制系统，设计了最小控制系统，绘制了电路原理图，编写了相应的控制程序，并进行了软件仿真分析。最终训练器实现了自由移动和减重功能，且减重装置高度可调、减重拉力大小可调，达到康复训练目的。63224

Title The design of a new electric walking trainer
Abstract At present, the Population aging of my country turns more and mare serious,and the people with Lower limb disorders become more and more,but the Lower limb rehabilitation of medical equipments are not mature,especially the Lower limb rehabilitation of medical equipments in standing way are lack,so the Lower limb rehabilitation of medical equipments in standing way need to be developed urgently.For the demand,a new electric walking trainer is designed in this thesis,include the mechanical system design and the control system design,and the overall structure of the walking trainer,the motion drive mechanism, the height adjusting mechanism for weight and the rope mechanism for weight are designed.At the same time, a stepper motor control system based on ATmega8 is builded,the minimum system is designed,the circuit schematics are drawn,the corresponding control programs are written and a software simulation analysis is conducted.In the end,the walking trainer realize the function of free move and bearing a burden,and the height of the system for weight can be adjusted,the tension of the system for weight also can be adjusted.Thus,the function of rehabilitation is realized.
