An improved mathematical model of the drive operation of dehydration of solid waste in the garbage truck is proposed, which takes into account the wear of the auger and allowed to numerically determine the dynamics of the drive during start-up. It was also established that increasing wear of the auger, the pressure of the working fluid at the inlet of the hydraulic motor rises, and the angular velocity and speed of the auger is significantly reduced. The research of this mathematical model was carried out using the numerical Runge-Kutta-Felberg method of the 4<sup>th</sup> order with a variable integration step. By means of the method of regression analysis, the power dependencies of the change of nominal values โโof pressures at the inlet of the hydraulic motor, angular velocity and speed of rotation of the auger from the value of its wear are determined. The last-mentioned dependence defines the detuning from the optimal speed of the auger during its wear and is used to determine the energy consumption of dehydration of solid waste, taking into account the wear of the auger.&nbsp;It is established that the wear of the auger by 1000 mm leads to an increase in the energy consumption of dehydration of solid waste by 11.6%, and, therefore, also leads to an increase of the cost of the process of their dehydration in the garbage truck.&nbsp;It was also established the expediency of further research to determine the appropriate material of the auger and the ways to increase its wear resistance.</p>}, number={2/100}, journal={Problems of Tribology}, author={Bereziuk, O.V. and Savulyak, V.I. and Kharzhevskyi, V.O.}, year={2021}, month={Jun.}, pages={79โ86} }
