dc.description.abstractThe article is dedicated to the analytical study of the improved mathematical model of the hydraulic drive of the mechanism for overturning a container with municipal solid waste into a garbage truck, taking into account the wear of friction pairs. As a result of the analysis of the performed numerical studies of the nonlinear improved mathematical model of the hydraulic drive of the mechanism for overturning a container with municipal solid waste into a garbage truck, taking into account the wear of friction pairs, a linearized version of this model was developed in the form of a system of ordinary linear differential equations of the 2nd order. To carry out design calculations of new garbage truck designs, approximate analytical dependencies were obtained for the pressure in the hydraulic cylinder pressure line, the angular velocity and the angle of container overturning on time were obtained based on the proposed linearized mathematical model of the hydraulic drive of the container overturning mechanism in the technological operation of loading municipal solid waste into the garbage truck during the 1st phase – overturning the container to the equilibrium position, taking into account the wear of friction pairs. A regression equation was obtained, which allows to approximately determine the duration of the 1st phase – the rotation of the container to the equilibrium position during its overturning in the technological operation of loading municipal solid waste into a garbage truck, taking into account the wear of friction pairs, which can be used during design calculations of new garbage truck designs taking into account the wear of working bodies without the need to study the nonlinear mathematical model of the drive, as well as during optimization of the main parameters of the hydraulic drive. It was established that the analytical study of the linearized improved mathematical model of the hydraulic drive of the mechanism for loading municipal solid waste into a garbage truck, taking into account the wear of friction pairs during the 2nd phase – pouring waste from the container into the body of the garbage truck requires further research.
