Abstract

This article clarifies the relationship between the phenomena occurring in hydraulic and electrical systems by comparing the processes of fluid flow in trunk pipelines and the processes occurring in power lines with distributed parameters. It turns out how it is possible to use the basic provisions of the electro-hydraulic analogy for the analysis of the technical condition of the lubrication systems, cooling and fuel supply of gasoline and diesel engines of autonomous and backup power plants and power plants of samples of armored and automotive vehicles. Hydraulic and electrical analogues are established, namely, fluid pressure and voltage, fluid flow and current, the hydraulic circle is represented as an electrical circuit, the concepts of hydraulic resistance, hydraulic inductance and hydraulic capacity are defined. It is proposed to consider hydraulic systems as dynamic links, changes in the values of which parameters should be used to assess the technical condition of gasoline or diesel internal combustion engines, using such physical quantities that characterize the operation of engine systems such as pressure and fluid flow, and determining the technical condition of these systems by identifying changes in the amplitude, frequency, phase and time characteristics of dynamic circuits created by hydraulic actuators resistances, hydraulic inductances and hydraulic capacitances. The purpose of this article is to substantiate the possibility of using electro-hydraulic analogies when evaluating the technical condition of diesel and gasoline engines. Using the method of electro-hydraulic analogy, which is based on the application of the theory of electrical circuits, for mathematical modeling of hydraulic systems, creating new or improved existing equipment of these systems, determining the features of their operation can significantly simplify the calculation of hydraulic circuits and also visually and simply perform an analysis of their work.
