Investigation the Motion of the Electromechanically Prosthesis for Human's Hip with Using Mathematic Model

Abstract

In article considered the construct and control of the electromechanically prosthesis for human's hip. It has a low cost for the consumer and more simple control system compared with foreign devices. Particular attention is paid to investigation of electric drive of the control system on stability. This problem is the important engineering task, which allows evaluating the quality of choice prosthesis’s elements. Also in article considered the investigation the dynamic motion of the electromechanically prosthesis of human's hip, which includes definition of the low changes of the torques of mechanism's joints, calculation the efforts created by power elements (the linear actuator and the mainspring), definition the speed of moving the output rod of the drive. The results of modeling the motion of the prosthesis allow determine the technical specification his power elements and design the program for control of the linear drive.
