Abstract
Abstract
The paper addresses the issues of stepless speed control of the hydraulic drive output link by means of frequency control, throttle control and pump-throttle control; they are compared, and their applicability in various types of hydraulic drives is analyzed [1, p.619]; a mathematical model of losses arising in a volumetric rotary hydraulic machine with volumetric (pumping) control and frequency management is given; a mathematical model is formed on the basis of which the dynamic characteristics of removable hydraulic drive with frequency control with varying parameters of external load and operating factors will be studied. The paper is based on theoretical research of the frequency-controlled hydraulic drive that was carried out [2, p.41]. As a result of the research, a schematic solution and a mathematical model of the developed hydraulic drive have been proposed. The main structural and technical and economic indicators are: a change in the angular velocity of the rotor of the machine in a given range, and an increase in the energy efficiency of the drive.
