CALCULATION OF HYDRO-MECHANICAL LOSSES AND MODELING OF CAVITATION IN THE CHANNELS OF THE HYDRAULIC UNIT OF A DUMP TRUCK
This paper shows the design process of hydraulic units used in hydraulic systems of mining dump trucks, taking into account the calculation of hydromechanical losses in the channels of the unit. Cavitation was calculated using the example of a channel section using the Ansys Fluent CFD analysis package, which was previously not taken into account when designing hydraulic blocks. A study was carried out of the influence of the roughness value and the diameter of the channel of the hydraulic unit on the size of cavitation cavities. Conclusions are drawn regarding the influence of the roughness value and fluid properties on hydromechanical losses.
