The article is dedicated to the improvement of the mathematical model of operation of hydraulic drives of
mounted sweeping equipment of a garbage truck, taking into account the wear of a cylindrical brush. An improved
nonlinear mathematical model of the operation of hydraulic drives of mounted sweeping equipment of a garbage
truck that takes into account the wear of a cylindrical brush, is proposed, which allowed to numerically study the
dynamics of these drives during startup and determine that taking into account the wear of the cylindrical brush
significantly affects such values as the pressure at the inlet of the hydraulic motor of the cylindrical brush and the
angular velocities of both hydraulic motors. At the same time, the pressure at the inlet of the screw conveyor
hydraulic motor after taking into account the wear of the cylindrical brush has hardly changed. The study of this
mathematical model was carried out using the numerical Runge-Kutta-Felberg method of the 4th order with a
variable integration step. It was also established the graphical dependencies to compare changes in the main
parameters of the hydraulic drive of the garbage truck’s mounted sweeping equipment during startup without
taking into account the wear of the cylindrical brush and with taking into account the wear. It has been established
that the creation of a linearized mathematical model of the operation of hydraulic drives of garbage truck mounted
sweeping equipment, taking into account the wear of a cylindrical brush, and its analytical solution in order to
obtain dependencies for an improved methodology for engineering calculations require further research.
