    Dependence of wear intensity on the coating material of the hydraulic cylinder of the garbage truck’s sealing plate
    (Хмельницький національний університет, 2024) Bereziuk, O.V.; Savulyak, V.I.; Kharzhevskyi, V.O.; Alekseiev, A.Ye.
    The article is dedicated to the study of the influence of the coating material on the wear rate of the hydraulic cylinder of the mechanism of the garbage truck’s sealing plate. By means of a first-order planning of experiment with first-order interaction effects using the Box-Wilson method, an adequate dependence of the wear rate of the hydraulic cylinder of the mechanism of the garbage truck’s sealing plate on the coating material was determined. It is established that according to the Student’s criterion, among the studied factors of influence, the intensity of wear of the hydraulic cylinder of the mechanism of the garbage truck’s sealing plate is most affected by the iron content in the coating, the least – by the chromium content, and the nickel content affects only indirectly in interaction with the iron content. The response surfaces of the goal function – the intensity of wear of the hydraulic cylinder of the mechanism of the garbage truck’s sealing plate and their two-dimensional sections in the planes of the influence parameters are shown, which allow to clearly illustrate the specified dependence of this goal function on individual influence factors. The expediency of conducting further research to determine ways to further improve the wear resistance of the hydraulic cylinder of the mechanism of the garbage truck’s sealing plate is shown

    Dependence of wear of friction pairs of the mechanism for loading solid household waste into a garbage truck on the characteristics of antifriction materials
    (Хмельницький національний університет, 2024) Bereziuk, O.V.; Savulyak, V.I.; Kharzhevskyi, V.O.; Serdiuk, O.V.; Yavorskyi, V.Ye.
    The article is dedicated to the establishment a regression dependence of wear of friction units of the mechanism of loading a garbage truck on the properties of antifriction materials. By using a first-order planning of experiment with first-order interaction effects using the Box-Wilson method, an appropriate regularity of wear of friction units of the garbage truck loading mechanism on the properties of antifriction materials has been determined. It is established that, according to the Student's criterion, among the studied factors of influence, the wear of friction units of the garbage truck loading mechanism is most influenced by the pressure in the friction zone, and the least – by the Brinell hardness of the antifriction material. The response surfaces of the objective function – wear of friction units of the garbage truck loading mechanism and their two-dimensional cross-sections in the planes of the influence parameters are shown, which allow to clearly illustrate the specified dependence of this objective function on individual influence parameters. It has been established that an increase in the pressure in the friction zone and sliding speed by 60% leads to an increase in the wear of friction units of the garbage truck loading mechanism during reverse motion by 6.3...34%, depending on the properties of antifriction materials. The expediency of conducting further research to determine ways to further improve the wear resistance of friction units of the mechanism for loading solid household waste into a garbage truck has been shown.

    Determination of the regularity of the rate of wear of the working hydraulic cylinder of the mechanism of the sealing plate of the garbage truck from the pressing force
    (Хмельницький національний університет621, 2024) Bereziuk, O.V.; Savulyak, V.I.; Kharzhevskyi, V.O.; Alekseiev, A.Ye.
    The article is dedicated to the study of the influence of the pressing force on the wear resistance of the working hydraulic cylinder of the mechanism of the sealing plate of the garbage truck. The usage of a mathematical dependencies and appropriate software programs for regression analysis made it possible to determine the exponential regularity of the change in the rate of wear of the working hydraulic cylinder of the mechanism of the sealing plate of the garbage truck depending on the pressing force. A graphical dependence of the change in the rate of wear of the working hydraulic cylinder of the mechanism of the compacting plate of the garbage truck on the pressing force was made up, which confirmed the sufficient convergence of the obtained regularity. Graph of the influence of pressing force on wear rate of working hydraulic cylinder of the mechanism of the compacting plate of the garbage truck demonstrates the expediency of its increase. It was established that for the garbage truck of Ukrainian production of serial model KO-436, the rate of wear of the working hydraulic cylinder of the mechanism of the sealing plate of the garbage truck according to the obtained regularity will be 0.257 μm/h. The expediency of conducting additional studies to determine further ways to increase the wear resistance of the working hydraulic cylinder of the sealing plate mechanism of the garbage truck has been established.
