MATHEMATICAL MODEL OF DYNAMIC PROCESSES IN HYDRAULIC SYSTEMS
Keywords:
mathematical model, hydraulic drive, distributed parameters, hydraulic drives, laminar, turbulent.Abstract
This article presents the developed mathematical model of a hydraulic drive with distributed parameters, taking into account wave processes, the flow regime of the liquid (laminar, turbulent), extreme operating conditions and a model of thermal processes in a flow hydraulic system. These models allow us to study the dynamic characteristics in the hydraulic drive, to determine the changes in the temperature of the liquid depending on the level of circulation in the flow system.
