Abstract: The paper presents a hydrodynamic analysis of the processes occurring in the flow of the working fluid in the channels of hydraulic units, hydraulic drive career the Autonomous dump truck, for example unit, providing the hydraulics of the braking system. The main attention is paid to the phenomenon of cavitation cavities and hydro-mechanical losses depending on the parameters of the working fluid and the geometric parameters of hydraulic channels. this article shows the sst-hl and ssg turbulence models. The Rayleigh Plesset cavitation model integrated into the ANSYS CFX software package is also presented.
