Research On Multi-modal Rehabilitation Training Platform Vibration

Strokee is a kind of cerebrovascular disease that threatens the health of theelderly, with high incidence rate, high death rate and mutilation recurrencerate higher several important characteristics. The lack of current medical resources inChina has many stroke patients didn’t to the best chance of early rehabilitation therapy.Rehabilitation training model currently single, with only some is not standardized,not fully, single type of exercise training, this caused more serious damage to the patient’sown. We need through innovation to seek more effective training methods and improve theefficiency of training.The research group for the rehabilitation of hemiplegic patients requirements,proposed a new multi model training platform, the platform is mainly composed ofa roll body, trim mechanism, the step chain. The platform can be for patients to completethe level, slope and step three modes of training. The smooth of therehabilitation mechanical products is directly related to the effect of the rehabilitation. Soit is necessary to analysis and optimize the vibration of the platform. In optimum design ofmechanical products, the dynamic performance is an important index. Vibration of structureis a quite important factor to consider in the work of rehabilitation medical machinery.We need to analyze and optimize the dynamic performance when studying its vibration.In this article the mode of dynamic performance of the rehabilitationtraining platform are studied, based on finite element technique, structure optimizationtechnology and mechanical kinetics, combined with mechanical design and theory. Thefinite element modeling and mode of the multi-model platform componentsand overall were analyzed, based on the finite element method. After the analysisof the mode and frequency, combined with the finite element method,the optimization principle of multi-mode platform is proposed. After the improvement ofthe structure of the optimization according to the principle ofoptimization, the dynamic performances are improved obviously and also verifiedthe validity of this principle.
