Abstract and keywords

Abstract:
The possibility of continuous monitoring of vehicle hydraulic fluids based on thermophysical parameters has been considered. The dependence of the thermophysical parameters of the working fluid on its oxidation, water content, and contamination with mechanical impurities has been identified. The proposed technical solution provides for the prediction of hydraulic system failures without disassembling the components or taking samples.

Keywords:
hydraulic fluid, automotive transport, continuous monitoring, thermophysical parameters, viscosity, mechanical impurities, oxidation, thermal conductivity, diagnostics of hydraulic systems
