Abstract

The main objective of this research is to describe the LS hydraulic drive based on a multimode directional control valve, for the most important operation of the hydraulic drive, to develop a mathematical model, to describe the developed mathematical model in the MATLAB system, to develop a software module in the MATLAB system for conducting theoretical studies of the mathematical model of the hydraulic drive. The subject of research is working processes in the LS hydraulic drive, a mathematical model of the LS hydraulic drive. Methods of mathematical modelling of differential equations of a nonlinear mathematical model, development of software module analytical methods were used in the research. The result of the research is the mathematical model of the LS hydraulic drive in the form of a system of differential equations and the scheme in the MATLAB Simulink system, which provided the solution of mathematical model equations and obtaining graphs of transients in a hydraulic drive. The algorithm for data exchange in the MATLAB Simulink system and the GUI graphical interface program, which implements data exchange, allows us to investigate the influence of the parameters of a load-sensitive hydraulic drive on the amount of overregulation by the pressure of the hydraulic pump in the hydraulic drive.
