Abstract During operation of the drive, the working fluid is exposed to various physical factors of operational and functional nature. At the same time, fluids lose their properties, degrade. This leads to a decrease in productivity and an increase in wear of the movable parts of the hydraulic drive, a decrease in its service life. When forcing hydraulic drives according to power or speed parameters, the dynamics of these processes grows. The paper analyzes various factors that have a negative impact on the operational parameters of the working fluid of hydraulic drives. Software tools of multidisciplinary analysis of models of basic elements of hydraulic drives are used as research methods. The results of simulation of hydraulic drive operating processes are given. Zones and parameters of working fluid degradation degree dependence on external and internal factors are localized. The simulation results using the experiment data make it possible to assess the positive or negative contribution of certain design and technological solutions and operational modes to improvement of the rheological and tribotechnical characteristics of hydraulic drive fluids.
Keywords hydraulic drive, working fluid degradation, modeling of working processes, multiphysics models
