Lower Limbs Exoskeleton Rehabilitation Training Robot Weight Reduction System Research

The result of the lower limb exoskeleton rehabilitation training robot is used to help becauseof stroke by neural damage cause paralysis of the lower limbs in patients with lower limbrehabilitation training equipment. In the training, because of the lower limbs of patients withcannot be completely under their own weight, weight reduction system to help patients to reducethe weight of the body of a patient, and at the same time keep in lower limb rehabilitationtraining process is always in the state of equilibrium.This article mainly discusses a kind of independent control of weight reduction system, it islower limb rehabilitation robot extremely important part, is to lose weight training necessarycondition.The concrete research content is as follows:1. Through the domestic and international lower limb exoskeleton rehabilitation robotweight support system research present situation analysis, especially for some existing weightreduction system done some analysis, points out its design, structural advantages, at the sametime points out the deficiency. Reference to its design advantages, and puts forward the subjectof weight reduction support system design basis, and some specific requirements.2. According to the principle of weight training on foot, function design of a independentcontrol of weight reduction support system. Weight reduction support system can be divided intovertical weight reduction, horizontal follow-up two parts, vertical weight reduction part mainlyunloading patients legs unable to withstand the body weight, horizontal follow-up part iscompleted in patients with lower limb according to predefined walking gait to follow themovement, complete the normal weight reduction gait rehabilitation training.3. To lose weight support system to establish mathematical model, and carries on thekinematics and dynamics analysis, the purpose is to explore weight training focus on foot with the motion law of nature and whether conform to walking for subsequent weight support systemcontrol strategy to prepare research.4. Using PRO/E software modeling, using ANSYS software to bevel gear do dynamics andstiffness analysis so as to achieve the purpose of optimization, which has the best parts ofmaterial distribution. The key parts of the mechanics analysis, check the security of the parts.5. Using the ADAMS software to complete the mechanism motion simulation, it isconcluded that weight loss control platform displacement, velocity, acceleration movementchange curve, and design of the reference data for comparison, so as to verify the rationality ofthe design.
