MATHEMATICAL MODEL OF THE BOOM LIFTING MECHANISM OF A FORESTRY HYDROMANIPULATOR WITH A MAGNETIC DAMPING DEVICE

An analysis of scientific and technical sources confirms that the problem of reducing dynamic loads and increasing the reliability of forestry machines remains relevant for the logging industry. As part of the study, an improved lifting mechanism of a hydraulic manipulator was proposed, which includes a magnetic damping device in its design, designed to reduce impact loads during operation. A mathematical model of the movement of the magnetic damper plunger has been developed, allowing us to describe its dynamics in the hydraulic drive system. The introduction of this technology helps to increase the reliability of hydraulic systems of forestry manipulators and reduce energy costs, which makes the operation of equipment more efficient.
