下肢康復(fù)機(jī)器人的設(shè)計(jì)與仿真研究
[Abstract]:As a result of traffic accidents, cardio-cerebrovascular diseases, aging population and other reasons caused by lower limb injury or paralysis seriously affected the patient's normal walking and quality of life. Recovery and improvement of lower extremity motor function not only need surgery and drug treatment, scientific, targeted rehabilitation training is essential. For rehabilitation training, a kind of lower limb rehabilitation robot is designed, which is simple in structure, flexible in use, light in weight, low in price and comfortable in wearing. The main contents of the research are as follows: through the study of gait theory of human body during normal walking, a gait training device of lower limb is designed. The length of the lower limb gait is designed to be stepless and adjustable for use by patients with different height and posture. The three-dimensional mechanical structure of gait training device is designed by CREO. The forward kinematics and inverse kinematics of lower limb gait training mechanism are analyzed by Cartesian coordinate system method. Compared with other kinematics analysis methods, Cartesian coordinate system method can obtain all position solutions of the mechanism without singularity. With the help of Simulink, the forward and inverse kinematics simulation module diagram is established. The trajectory curve of the foot center at the end of the leg of any human lower extremity can be obtained by simulation. Meanwhile, the hip and knee can be quickly obtained when training according to any predetermined gait trajectory. The curve of curvature, extension angle, angular velocity and angular acceleration of ankle joint in a motion cycle solves the complex calculation problem and provides a new way for the simulation of mechanism. The dynamic analysis of the mechanism is carried out by Lagrange method, and the expressions of the torque of the hip, knee and ankle joint are obtained. The dynamic simulation module diagram of the mechanism is established by Sim Mechanics, and the torque curves of the hip, knee and ankle joints of the robot are obtained quickly by the simulation. The movement space and dexterity of the gait training organization are analyzed. The effects of height and motion angle of hip, knee and ankle on motion space were analyzed. According to the condition number index of Jacobian matrix, the distribution pattern of dexterity of lower limb gait training institutions is obtained by MATLAB programming, which can be used as a reference for structural design.
