Abstract: The relevance of the work is due to the fact that the hydraulic drive working fluids are a mixture of liquid and undissolved gas.
Such a mixture can be formed when filling the tank and during dynamic processes due to different rates of dissolution and gas release
from the liquid when the pressure drops in certain sections of the working medium flow. The task of this work is to create an
analytical method for controlling the influence of the amount of undissolved gas on the dynamic processes of the hydraulic drive of
self-propelled machines, by writing and analyzing a mathematical model. The results of mathematical modeling were confirmed
experimentally on the developed stand
