Mathematical modeling of dynamic processes of control system of hydraulic drive of belt conveyor with variable load

Abstract

For built-in hydraulic drive of belt conveyor which is equipped with two hydraulic motors mounted in parallel a control system is proposed in order to activate the second hydraulic motor when the load exceeds the rated load by a given value. The control system duty cycle diagram and computational scheme are developed, differential equations are composed, which describe a movements of its movable masses as well as fluid balance equations for phases of forward and backward strokes of shut-off-and-regulating element and unambiguity condition.
