     Abstract. The paper is devoted to the creation of an improved model for the abrasive granule interaction with part internal surface during vibroabrasive processing. The reasons for the differences in the processing of the external and internal surfaces of the part are revealed. Improved mathematical models have been obtained for determining the volume removed per single interaction and the maximum depth of granule penetration. As a result of the research, the adequacy of the proposed dependencies was confirmed. The resulting dependencies can be used in the automation of engineering calculations in digital production.

    Keywords: vibroabrasive processing, single interaction, penetration depth, material removal, roughness, surface position.

    Annotation. The relevance of increasing the efficiency of a logging vehicle by using regenerative shock absorbers in the design of its suspension is substantiated. The analysis of scientific works of foreign authors involved in research in the field of recuperation of various types of energy in the shock absorbers of vehicle suspensions has been carried out. Possible options for the appearance of a disturbing force and deformation in hydraulic shock absorbers and elastic suspension elements of a logging vehicle during its movement along an insufficiently equipped logging road are described. A mathematical description of the processes occurring in the suspension system of a timber vehicle equipped with hydraulic shock absorbers and spring suspension is presented. The dependences of the change in the power dissipated by the hydraulic shock absorber in various frequency ranges are given. A perspective scheme of a linear electromagnetic generator installed in the suspension of a timber vehicle is proposed. Its device, principle of operation, as well as advantages are described. The tasks are formulated, the solution of which will allow the prototype of the modified design of the regenerative shock absorber to be put into mass production.

    Annotation. Coordinated management is one of the ways to improve the efficiency of main streets, using a coordinated management mode, it is possible to reduce the occurrence of major adverse situations on the managed section of the road network - long downtime, unintended delays, and even accidents. But in the conditions of modern cities, situations often arise when the intensity in the connecting sections is quite high and exceeds the intensity in the coordinated section, in this case, the effectiveness of management must be assessed. In this regard, the main goal of the study is to evaluate the efficiency of the coordinated section, taking into account the variation in intensity indicators, both in the main section (main street) and in connected sections.

    Keywords: COORDINATED MANAGEMENT, MAIN STREET, CONNECTED AREAS, EFFICIENCY, TRAFFIC INTENSITY.
