Electric-hydraulic converter simulation and testing

Abstract

The aim of this work is to create a simulation model of electro-hydraulic converter with operates the hydraulic system of two hydraulic actuators, and to conduct tests of the electro-hydraulic converter in laboratory conditions. The work also includes the creation of a simulation model of a system of two hydraulic actuators, a load sensing pump and a proportional directional control valve. In the research, models for the two systems in question have been created and verified by comparing the simulated data with that experimental obtained in the laboratory tests. Based on the verification results, the modes of operation are formulated in which the behavior of the model most closely repeats the behavior of a real physical system, the directions of development of models are listed, and the effectiveness of systems with an electro-hydraulic converter and with a load sensing pump are compared.
