Abstract

The article presents a method for artificial damping of the dynamic system of a mobile sinking hoisting plant, involving reduction of dynamic loads in elastic elements of the hoisting plant with a gearless, high-torque hydraulic drive, based on introduction of a proportional pressure valve in the hydraulic system, providing overflow of hydraulic fluid from the pressure line to the drain one in transient acceleration and deceleration limiting the amplitude of the differential pressure on the hydraulic motor by forced application of defined pressure in the pressure line, implementing a flexible dynamic pressure feedback.

Keywords

Hoisting plant, gearless hydraulic drive, flexible negative feedback, proportional pressure valve, dynamic loads.
