Abstract
This article presents the results of the analysis of the creation and operation of multi-wheeled vehicle filling stations for the significance of creating a generalized methodological apparatus in order to ensure a sustainable reduction in the risk of accidents, explosions, man-made disasters and reduce the mortality of people at gas stations. More and more people are killed, injured and burned if fire safety measures are not followed when refueling large multi-axle wheeled vehicles. Accidents and explosions cause significant damage directly to the gas station itself, as well as to tankers carrying explosive fuel and substances. The substances used are mainly characterized by fire and explosion hazards. Therefore, in addition to pollution of environmental objects such as soil, air and water resources, and, as a result, changes in the ecosystem, further fire or explosion is possible. In this case, there is both an energy impact on neighboring objects, and their possible destruction. This article discusses the indicators of accidents in the event of accidents on vehicles, primarily on tankers, a preliminary assessment of the consequences of accidents and the possibility of taking measures to prevent the factors leading to them. The creation of a generalized methodological apparatus for assessing the consequences of accidents will make it possible to assess emerging emergencies without dividing them into classes of transported substances.

Abstract
The article presents a method for assessing the permissible speed of a particularly heavy-duty vehicle based on a road train using a combined hydraulic transformer in the tractor transmission, as one of the indicators of cross-country ability. In this paper, we consider one of the main ways to increase the cross-country ability of heavy-duty vehicles: the creation of heavy-duty vehicles based on a road train with an active trailer link. Increasing the passability of heavy-duty vehicles is primarily aimed at increasing the permissible speed of heavy-duty vehicles and the maximum angles of ascents to be overcome. When justifying the choice of an algorithm for controlling the voltage of a torque Converter inductor based on the speed of particularly heavy-duty vehicles, it is advisable to use the external characteristics of the torque Converter as evaluation indicators: the dependence of the efficiency coefficient, the dependence of the moment created by the pump, and the dependence of the transformation coefficient on the gear ratio of the torque Converter. As criteria for evaluating the feasibility of using a combined torque Converter for especially heavy-duty vehicles, it is advisable to use the maximum increase in efficiency, the moment created by the pump wheel, and the transformation coefficient of torque converters on magnetic fluid in relation to the efficiency, the moment created by the pump wheel, and the transformation coefficient of the torque Converter based on a conventional working fluid in the operational range of gear ratio changes. The external characteristic is calculated after calculating the blade system and selecting the design to determine whether the main parameters of the characteristic correspond to the parameters specified in the task for designing the torque Converter. Such calculations often have to be performed when fine-tuning torque converters with a known design, when the influence of geometric parameters of individual elements of the blade system (input and output angles, wheel radii, the number of blades in the impellers, etc.) on the transforming and loading properties of the torque Converter is investigated.

Published: July 2021

Abstract
The article analyzes the types, methods and techniques of parts processing at restoration and quality criteria of parts of cars, other vehicles and road-building machines in terms of efficiency. Correlations between the quality criteria and the functionality of the part have been established, for which the requirements for machine safety and reliability after the restoration of individual parts have been taken. A mathematical model has been developed in the form of an algorithm for selecting the best variant of the restoration technology for a functionally important part, based on a typical restoration technological process, which consists in the development of a multi-criteria problem, the initial postulates of which are matrices: W “wear resistance → durability”; S “safety → reliability”; F “part fragility → machine safety”. New parameters in the form of coefficients describing roughness, hardness and riveting of a part have been proposed. In particular, the authors define the coefficient of technological isotropy of roughness, which evaluates the roughness parameters in the process of technological changes of a part; the coefficient of isotropy of hardness, which compares the hardness parameters on the surface of the part and in the core of it; the coefficient of intensity of hardness, which is a complex parameter and in which there is a change of hardness by the depth of the part and the value of hardness depth (riveting). The purpose of introducing these coefficients is consistent with the model being developed to select the optimal technology for restoring parts of cars, other vehicles and road-building machines.

Published: July 2021

Abstract
The article is devoted to the application of the tensor basis for the analysis of uncertainties in decision-making in freight transport ULS-systems. The use of tensors for constructing a mathematical model of the coordinator in the decision-making system is shown. Tensor equations make calculation possible the system parameters for any change in the structure of connections in the basic mathematical model. This provides additional advantages when making decisions in an uncertain environment. The authors also demonstrate the use of a tensor apparatus for constructing a mathematical model of deep uncertainty, which is impossible with traditional methods of analysis. The article shows that tensor analysis can be used to model decision-making under conditions of deep uncertainty in complex conditions, such as a catastrophes. Representing a fuzzy variable as a tensor makes it possible to explore additional properties of this variable. Tensors describing additional properties of the fuzzy variable (deviator, spherical tensor, symmetric tensor, and antisymmetric tensor) can be obtained from the fuzzy variable tensor. Applying special calculations to a fuzzy tensor variable makes it possible to obtain the membership function with high accuracy and find the defuzzified output value of the membership function. Tensor analysis significantly expands the scope of ULS-systems research.

Published: July 2021

Abstract
In the years ahead, one of the most important tasks of the government of the Russian Federation is to bring the condition of highways of various categories to standard parameters and ensure their safety. This is reflected in the decrees of the President of the Russian Federation and in national projects, for example, in the national project on “Safe and High-Quality Roads”. In order to ensure safety and reduce damage from road traffic accidents on highways, various measures are used, including the installation of technical means of road traffic organization. These measures include cable barriers, which also have become popular recently. According to numerous studies, this kind of barrier has a positive effect on the passive safety of highways and it reduces the number of accidents with serious consequences that occur as a result of vehicles driving in the oncoming lane. However, the incorrect installation of these barriers (non-compliance with the minimum safety lanes at barriers, improper installation of barriers when the number of traffic lanes changes, etc.) and imperfection of the modern regulatory framework can negatively affect both a driver and the traffic flow in general, leading to the increase in the number of road traffic transport accidents. This is explained by the fact that a driver of a car, being afraid of close movement along the cable barriers at high speed, tries to stay away from the barrier as far as possible, increasing the side clearance between the vehicle and the barrier. However, at the same time, the side clearance between vehicles passing in the right lane (where a driver has limited visibility) or any obstacle on the right (for example, cars standing on the side of the road) sharply decreases. The article considers the results of the study of changes in the side clearance between the centre line of a road in the presence of a cable barrier and in its absence. The measurement results were compared. According to the results of the measurements, the authors gave the recommendations to improve road conditions, safety and the recommendations for further study of this issue.

There were determined such parameters as the optimal ratio of concentrations of electrolyte components – 150 g/l of iron chloride (2) and 50 g/l of chromium sulfate (3) and modes of electrical recovery of metals – current density 40 A/dm2; the temperature of the electrolyte is 50°C, the acidity of the solution is 0.5 pH units, which contribute to obtaining a high-quality coating with high tribological characteristics. Assumptions are made about the mechanism of the alloy formation by electrolysis from a mixed electrolyte.

Authors: Chudina O V , Luzhnov Yu M 
Published: July 2021

Abstract
The concept of surface hardening of structural steels is proposed on the basis of the structural theory of strength and the Charpy principle at the macro-and microgeometric levels for the purposeful formation of a structure that can effectively resist wear and fatigue. An intellectual approach to the rational choice of technological combinations capable of maximally realizing the dislocation, substructural, grain-boundary, solid solution and dispersion mechanisms of steel hardening, which makes it possible to create optimal structures on the surface of tribo-interface elements, is described. As an example of such an approach, the surface laser alloying of structural steels with nitride-forming elements with subsequent nitriding was investigated; an increase in surface hardness, strength, wear resistance by 15 times and fatigue strength by 1.5 times compared with the initial parameters of steels was shown.

Published: July 2021

Abstract
The article deals with the application of process typification in the restoration of the most worn-out parts of cars, other vehicles and road construction machines from the point of view of application of optimization of the best quality parameters selection. A typical technological process of part recovery using the solution of a multi-criteria dynamic problem by the zoning method has been proposed with the introduction of the best variant of the matrix technology into the algorithm of selection: W “wear resistance → durability”; S “safety → reliability”; F “part fragility → machine safety”. The goal is to achieve maximum efficiency in structuring the technological process of restoration of parts of cars, other vehicles and road construction machines according to a number of reasonable criteria. While solving the task, the analysis of the existing methods of modeling for solving such tasks has been performed. The authors proposed their own solution in the form of an algorithm of the zoning method based on the principle of compliance with the hierarchical correlation of probabilities of possible states of the external environment in order to select an optimal variant of the required solution. As a result, it has been found that obtaining the maximum efficiency of the technological process of shaft-type parts restoration in cars, other vehicles and road construction machines can be solved by the task of dynamic programming as determining the optimal trajectory of the part transitions during the restoration process.

Abstract
The article proposes the structure of the Crushing and Screening Digital System (CSDS). A software implementation of a digital system for a cone crusher has been completed, which allows integrating a set of interfaced technological units in the control of one hardware equipment as part of the controller and installed at the operator station of the SCADA system. The most important functions of the CSDS are the continuous monitoring of the equipment condition of the complex of crusher mechanisms and aggregates in the process of work and the formation of a signal to regulate the productivity of the crusher. CSDS allows you to integrate in the control of one hardware as part of the selected controller and the SCADA-system server crusher installed at the operator station, a set of interfaced technological units, the efficiency of joint work of which is largely determined by the degree of coordination and the speed of two-way information exchange. In the event of malfunctions or abnormal situations, it will notify the operator. All accidents and crusher operation parameters are recorded in an electronic archive. The developed system provided a significant increase in the operator’s comfort, providing him with a single user interface for controlling the cone crusher from one operator station and an additional amount of information and services.

Authors: Petrova L G , Demin P E , Sergeeva A S , Timofeeva G Y 
Published: July 2021

Abstract
In the paper modernized techniques of zinc metallization of steel in combination with nitriding are considered. Two methods of combined surface modification of low-carbon steel are studied: application of zinc coatings by painting technique and subsequent gas nitriding; simultaneous thermo-diffusion saturation by zinc and nitrogen. Microstructure and microhardness of steel samples were examined; forming of a transition zone was determined under visually observed surface layer/coating with increased concentrations of Zn and N. Combined saturation by zinc and nitrogen forms diffusion layers with increased wear resistance and reduced friction coefficients together with improved corrosion resistance in salt fog. Nitriding of Zn coatings protects the steel both in salt and acid mediums.
Analysis and mathematical modeling of cable barrier mechanics during car impact
Authors: Demiyanushko I V , Karpov I A 
Published: July 2021

Abstract
The article discusses the mechanics of the response of cable barriers used in Russia. The first part of the article describes the general mechanics of the barriers. The second part describes the mechanics of the open-type posts, the most commonly used type worldwide. In the third part, accidents with closed-type posts are classified. The latter are unique structures that were developed in Russia to significantly reduce the deflection of barriers (by 35-50%). Understanding the principles of their response is not required for the further development of their structure only but also for the creation of their digital models since accurate models can only be developed if key physical processes are taken into account.

Authors: Rementsov A N , Egorov V A , Vu Fan An 
Published: July 2021

Abstract
Over the past decade, the economies of Southeast Asian countries, including Vietnam, have been developing dynamically, which leads to an increase in demand for the transportation of goods and passengers. At the same time, in a number of countries in this region, there is no state regulation in the field of rationing fuel consumption of trucks in real conditions. Therefore, improving the current fuel rationing system is an urgent task when performing cargo transportation in the tropics. The paper offers a justification for rationing fuel consumption of trucks performing transport work on permanent routes in tropical conditions on the example of Vietnam.
