Development and optimization of the control device for the hydraulic drive of the belt conveyor

Abstract

Designing new hydraulic equipment requires consideration of the peculiarities of the operating modes of the technological machines. This particularly applies to the hydraulic drive of a belt conveyor, which operates under variable load conditions. Therefore, investigations aimed at reducing static and dynamic characteristic indicators, design calculations, as well as three-dimensional modelling, are relevant tasks for engineers and scientists. Various optimization methods for dynamic processes have been considered. Preference has been given to the linear programming method as the main one for optimizing dynamic processes in the hydraulic drive under overload conditions. Fundamental schemes of the belt conveyor hydraulic drive and control device have been developed and their principles of operation described. Nonlinear differential equations in Cauchy form have been formulated and solved using the MATLAB Simulink software package. A comprehensive criterion for optimizing the static and dynamic characteristics of the belt conveyor hydraulic drive has been developed. Graphs of dynamic processes before and after optimizing static and dynamic characteristics have been provided depending on the parameters of the control device construction. The minimum value of the comprehensive criterion optimization corresponding to rational parameters of the control device construction has been calculated. Based on these parameters, a three-dimensional model of the control device has been developed. The obtained research and calculations will be useful for engineers and scientists during the development and design of new hydraulic equipment.
