Стійкість гідроприводу стрічкового конвеєра, чутливого до зміни навантаження

Abstract

The stability of the hydraulic drive of a conveyor belt sensitive to change in load, taking into account the parameters of the hydromechanical drive system, its control system and the elastic-inertial characteristics of the conveyor belt conveyor using the computer software package MATLAB Simulink, is researched. The areas of stable and unstable operation of the drive for changing the parameters of rigidity and damping coefficient for the sensor, valve-distributor and pressure plunger of the control system are revealed. The analysis of theoretical graphs specifies the characteristic volume of the additional hydromotor, the ratio of the areas of sealing of the stopper element of the sensor, which affect the stability of the drive. It is determined that the nature of the load change does not affect the stability of the adaptive drive of the belt conveyor.
