Simulation of dynamics processes of hydraulic system with axial-reciprocating piston pump and electrical engine

Abstract

In the article the dynamic processes in an axial-reciprocating hydraulic pump and asynchronous engine are considered. The mathematical model of an axial-reciprocating hydraulic pump is presented, where the flow of fluid in each cylinder of the pump and the interaction of liquid with the piston are taken into account. The flow of fluid in a hydraulic system is described by a system of equations of a hyperbolic type, which is solved by the characteristics method. For example, the mathematical simulation of the activity of an axial-reciprocating pump in a hydraulic system together with the mechanical drive is shown.
