INFLUENCE OF TECHNOLOGICAL FACTORSFOR THE QUALITY

The article contains a study of the influence of technological factors on the formation of a film antifriction coating when applied to parts of cars and cars. The article presents a methodology and results of calculating the adhesion strength of a film coating with a steel base. The equipment used to determine the adhesion strength is presented. The technique of using the specified equipment is described. The dependence of the adhesion strength on the modes of film coating is established and described. Recommendations have been developed for the selection and method of applying film antifriction coatings during the maintenance and repair of motor vehicles.

INFLUENCE OF SOLAR RADIATION ON THE MICROCLIMATE IN THE CAR INTERIOR IN THE SUMMER

The value of illumination in the cabin is determined, at which there is a sharp deterioration in the situation in the cabin. The results of the study can be used to determine the optimal darken-ing of windows, the effectiveness of the use of athermal coatings and the operation of the climate plant.

METHOD OF REPLACEMENT OF SPARE PARTS FOR MAINTAINING AND ENSURING OPERATING STATE OF MOTOR TRANSPORT

A method based on the sequential implementation of a formalized description of the process of consuming spare parts, a formalized description of the process of determining the state of the el-ements of a market system, a formalized description of the process of determining a rational route for transporting the necessary material and technical means is presented.

VIBRATION PROTECTION SYSTEMS OF VEHICLES: ACTIVE CONTROL AND OPTIMIZATION

The article presents the results of studies of the dynamic properties of a vibration-protective system with active control, which is directly identified with the compensatory effect and is charac-terized as direct control, as well as a vibration-protective system with indirect control, which forms a compensatory effect mediated through the implementation of an intermittent process of changes in the parameters of the inertial link. To find the optimal positional control function of direct (ac-tive) control, as well as indirect (singular) control of the inertial link, information technologies for solving boundary value problems were used in relation to the canonical Hamilton equations for the vibration protection systems under study. The parameters are established at which vibration protection systems of this type eliminate resonance phenomena and provide comparable indicators of vibration safety for protected objects under kinematic disturbance.

PASSIVE SAFETY OF MOTOR TRANSPORT DEPENDING ON THE

The interrelation of thermal modes of brake units of transport vehicles on their reliability and durability depending on operational factors of transport is considered. It is assumed that all the kinetic energy of rotating and translationally moving masses in the brake nodes is converted into thermal energy. In this regard, a criterion is used that characterizes the thermal energy released in the brakes and the operational criterion of transport vehicles. Comparison of these criteria makes it possible to evaluate the performance and durability of brake components, as well as to outline ways of their structural perfection depending on heat dissipation.

TRANSPORT INFRASTRUCTURE ADAPTATION

The transition of a city to the «Smart city» level is a socio-technical process: first, the transi-tion includes technical and technological changes, and second, since the city is a social system, this process considered from the point of view of users who influence the development of certain types of services and devices for their provision. This article examines the process of digitalization of the city and transport infrastructure in particular. To fulfill the goal set for the transport infrastructure - complete, timely and high-quality transport services for the population, it is necessary to solve a whole range of tasks that are associated with the further development of market relations and improving the efficiency of the transport complex.

MODEL OF ACTIVITY OF A CANDIDATE FOR DRIVERS IN THE SYSTEM «CADET-CAR-ROAD-TRAFFIC ENVIRONMENT»

Presents a model of the activity of a candidate for drivers in the system «Cadet-Car-Road-Traffic environment». The main factors that have a direct impact on the formation of safe behavior skills while driving a vehicle at the stage of professional training of driving personnel are identified, which are: the probability of trouble-free, error-free, and timely performance of operator tasks.

LABORATORY WORK AS A MEANS OF ACQUISITION OF PROFESSIONAL SKILLS FROM TRANSPORT SPECIALTY STUDENTS

The article examines, using the example of the laboratory work «Dismantling an internal combustion engine», the acquisition of skills in the maintenance and repair of motor vehicles from students of transport specialties. The methodology of laboratory work and methodological support is presented. Based on the testing of students, a conclusion was made about the possibility and ef-fectiveness of conducting full-scale laboratory work. Recommendations on laboratory work for students of transport and related specialties are given.

ANALYSIS OF THE INFLUENCE OF ELEMENTS OF THE DIESEL COOLING SYSTEM ON ITS THERMAL STABILIZATION BY MEANS OF COMPUTER MODELING

Logistics support of products at all stages of the life cycle is gaining increasing influence. This is facilitated by the increasing complexity of structures, a large number of elements, the intro-duction of mechatronic systems. Under these conditions, the relevance of developing methods for analyzing the design of samples increases. The developed model for analyzing the diesel cooling system is based on the principles of cognitive modeling. The practical significance of cognitive models is shown, which consists in the possibility of predicting changes in the influence of system elements on the target function in various operating conditions.

THE PROJECT OF TRAFFIC ORGANIZATION AT THE ENTRANCE TO THE CITY OF SHAKHTY FROM THE M-4 "DON" HIGHWAY

The analysis of the existing traffic was carried out, a new scheme of traffic organization at the intersection of Mayakovsky street - Chkalov street was proposed, calculations of traffic light cycles at these intersections were carried out, taking into account the introduction of new traffic light objects. The results of the research will solve a number of problems of the road complex of the city of Shakhty to improve the transport and operational condition of the existing network of pub-lic roads of local importance and structures on them. To bring technical parameters and levels of engineering equipment of roads in compliance with the reached sizes of intensity of traffic.
