The problem of accelerating and reducing the cost of road construction without reducing their quality can be solved by creating a complex of continuous units. The units, following each other, carry out the whole range of works aimed at the construction of roads. One of the elements of the continuous unit that forms the cuvette is a direct-flow rotary ripper. It was revealed that for excavation near the axis of rotation of the rotor of a direct-flow rotary ripper, a small rotor with a higher angular velocity should be installed, coaxially with a large rotor. The small rotor contains: a small rotor tip with spiral blades, two teeth and two knives. One of the elements of the small rotor is a spiral blade. The interaction with the soil of spiral blades has not been sufficiently studied. The method of research. The interaction with the ground of the tip of a small rotor with spiral blades is considered. The angles of inclination of the first and second turns of the spiral are determined by the construction of the scan. The following assumptions are made: the ratio of the forces acting on the part of the cone with the spiral to the part of the cone without the spiral is equal to the ratio of the lengths of the cones forming these parts; The spiral blade does not slow down the unit and does not accelerate it, that is, the sum of the forces that counteract the introduction of the cone into the ground balances the forces that introduce the cone into the ground. The sum of the conditional normal reactions of the cone to the impact of the soil is equal to the product of the resistivity of the soil and the surface area of the cone and the coefficient that takes into account the increase in the resistivity of the soil as it is compacted by the cone.Results. On the basis of the methodology, calculations and constructions were made. The area of the front surface of the turn of the spiral blade is approximately equal to the product of the height of the turn and the length of its midline. By construction, the length of the midline of the turns was revealed. The dependences of the length of the spiral on the height of the turn of the spiral blade are shown in the figures. The limits of the angles of inclination of the base of the first and second turns of the spiral blade are established. The height of the turn blade is determined. Conclusion. The angles of inclination of the first and second turns of the spiral are determined by constructing the scan. By constructing projections on the transverse-vertical plane, the lengths of the middle lines of the spiral blade spins are determined. Based on the calculations, taking into account wear during operation and distortion of the projection of the spiral on the transverse-vertical plane, the height of the spiral blade is 10 mm.","PeriodicalId":32892,"journal":{"name":"Vestnik SibADI","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44405832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the introduction of new amendments to the rules of the road, accidents involving personal mobility device (PMD) continue to occur on the roads of the Russian Federation. The analysis of statistical indicators makes possible to determine that more than 90% of accidents occur in populated areas, with the participation of PMDs equipped with electric motor mainly collisions with vehicles, with less powerful, not equipped with electric motor mainly collisions with pedestrians occur, which indicates certain chosen conditions for driving - the roadway and sidewalks. In addition, it was found that in these cases, one of the emerging types of accidents is tipping, associated primarily with the available elements on sections of city streets and city roads, which have a certain height above the level of roads and sidewalks.

The process of planning public transport is divided into a few number of tasks in strategic, tactical and operational levels, which include the development route system, the establishment of traffic intensity along routes, the design of the structure of road transport vehicles, the distribution of the current road transport vehicles along the routes, determining the required amount of the subsidies, etc. Materials and methods. The article presents a multi-criteria mathematical model of transportation design, according to which the tasks have been solved by distributing (limited or unlimited) transport resources between the permissible routes of the transport network in accordance with a variety of efficiency criteria, which can be the subject to appropriate restrictions. The formation acceptable routes on the transport network can be carried out by means of the algorithms developed, for example, in the framework of solving TNDP and TNDFSP tasks. The routes can also be adjusted by experts. Transport demand is set by a matrix of passenger correspondence generated for the entire period of traffic on a weekday, to ensure that all passenger flows along the route network are taken into account, and not only the periods of the greatest traffic intensity. The calculation of the parameters of the transport offer in the process of solving the problems of transportation design is carried out based on the results of the passenger correspondence distribution on the route network (PAP), which is a complex problem unsolved today. The article describes the developed PAP methodology based on a flexible passenger strategy that takes into account the waiting time for transport, the proximity of the route through an empirical model of dividing demand by the length of trips, the preferences of transport modes, the possible redistribution of passenger flows between the stopping points of the network located within a walking distance. Results. The tasks of designing public transport transportation have been formulated, a multi-criteria mathematical model of their solution has been developed. The method of distribution of passenger flows on the route network based on a flexible passenger strategy has been described. The effectiveness of the developed PAP methodology is shown on test calculations, which were carried out using passenger correspondence, an average weekday in October 2019, obtained by processing validations of e-tickets of urban passenger transport in Krasnoyarsk.

The long network of pipelines on the territory of our country needs timely and high-quality repairs. The entrenching tool used so far increases the complexity of work on the overhaul of pipelines, which forces to create solutions for mechanizing the process of digging the pipeline.

A general view of the working equipment with the designation of the positions necessary for the study is given. Methods and materials. The concept of specific values of torque and power per one cutter of working equipment has been introduced. The dependencies of the total productivity of the cutters and the torque of the cutters are established.

At the initial stages of designing snow blower feeders, it is necessary to have relatively simple ratios on the basis of which one can judge their efficiency and their potential. The presence of such indicators makes it possible to reasonably choose the design scheme, geometric and kinematic parameters of the working bodies of rotary snowplows. The solution of such problems, in turn, can significantly reduce the time for designing machines and their working bodies. Thus, the main goal of this study is to assess the possibility of substantiating the effectiveness of design solutions for snow blowers in the early stages of design. Methods and materials. To achieve this goal, such tasks as the substantiation of the indicators on the basis of which the effectiveness will be assessed, description of the mechanism for obtaining their theoretical values were solved.

The equations for the lengths of the trajectories of motion of an arbitrary point of the cutter of the feeder of a rotary snowplow are obtained for its vertical and horizontal arrangement. The equations make it possible to determine the duration of the interaction between the transported snow mass and the working equipment from the moment of its capture to the moment of its unloading.

One of the urgent tasks facing the developers of land transport and technological machines is to reduce the vibration effects on the human operator. Vibration impacts are caused mainly by the interaction of the working bodies with the working environment and the running equipment of machines with the microrelief of the supporting surface on which the machine moves. To reduce vibration impacts, vibration protection systems of the cab and operator’s seat are used. The designs of vibration protection systems of seats with the effect of quasizero stiffness are promising. The design of a passive vibration protection system of an operator’s seat based on a parallelogram mechanism, which makes it possible to provide the specified effect of quasi-zero stiffness, is proposed. For practical application of the developed vibration protection system of a seat, it is necessary to solve the problem of assignment and optimization of its main design parameters.Materials and methods. RMS vertical acceleration of a seat in a stationary coordinate system was taken as the target function for optimizing the design parameters of the vibration protection system of a seat. For the developed calculation scheme of the seat vibration protection system based on a parallelogram mechanism, independent design parameters that influence the mean square vertical acceleration of the seat were identified. To reduce the dimensionality of the problem, some of the parameters were bound by algebraic dependencies, or fixed. The need to reduce the number of independent varying parameters was due to the relatively long simulation time of the individual process of moving the machine along the microrelief of the supporting surface using the developed complex simulation mathematical model of a motor grader with vibration-proof supports of the operator’s cabin and with a vibration-proof mechanism of the operator’s seat. The horizontal length of the parallelogram link, the ductility factor of the damper mechanism, and the horizontal dimension from the rotation axis to the limiting rollers of the mechanism were selected as independent.Results. A methodology for selecting and optimizing the design parameters of the vibration protection mechanism, presented in the form of a flowchart, which includes the stage of local optimization of the viscosity factor of the damper and the horizontal dimension from the axis to the limiting rollers by the Simplex method, has been developed. Obtaining each individual value of the target function in the local optimization was performed by processing the results of discrete values of seat acceleration obtained by simulating the movement of the machine on a simulation mathematical model.

This article discusses the technology of designing asphalt concrete pavements, using the Superpave method. The Superpave (SUperior PERforming Asphalt PAVEments) system was developed by the Strategic Highway Research Program (SHRP) in the USA. The aim of the program was to find new ways of designing asphalt concrete pavements that will work better at extreme temperatures and heavy traffic loads.Currently, the system of volumetric design of asphalt concrete mixtures is being actively implemented in Russian road construction industry. This is an adaptation of the American Superpave method and is being implemented in our country in the form of a series of new standards. The Superpave volumetric and functional design system in particular addresses several pavement-related problems: permanent deformation, which results from poor asphalt mix shear strength at high temperatures, and low temperature damage, which occurs when the asphalt pavement is subjected to stress exceeding the compressive and tensile strength. The elimination of the above problems is carried out due to the most reasonable selection of the components of the asphalt concrete mixture.Materials and methods. Studies of bitumen binders were carried out according to the methods laid down in the technical requirements: GOST R 58400.1-2019 Public roads. Materials binding petroleum bitumen. Technical requirements taking into account the temperature ranges of operation.The selection of the PG brand of bitumen binder using Superpave technology was carried out using the example of a polymer-bitumen binder that meets the requirements of GOST 52056-2003 PBB 90 (sample 4) and a bitumen binder obtained from tar with the addition of thermoplastic elastomer (hereinafter referred to as TEP) of the SBS type that meets the requirements of GOST 52056-2003 PBB 90 (sample 3).Results.

The formation of a ‘cargo frame’ around large cities leads to a change in the composition of the traffic flow on bypass roads, and an increase in the total traffic flow of trucks of various categories.

The totality of the reflected phenomena leads to the emergence of a certain kind of transport problems, primarily associated with a decrease in throughput. Quite often, such problems are observed at regulated intersections, which requires a prompt change in the control mode; for this, the necessary measure is the mandatory consideration of the technical and dynamic parameters of trucks, which are not fully taken into account in the existing reduction factors.

During the combustion of diesel fuel in a diesel engine with an increased fuel supply, as a result of its incomplete combustion, soot particles are formed, which are either released into the atmosphere or inevitably enter the engine oil. Soot, polluting the engine oil, causes a change in its quality indicators. Soot is very small particles formed by a complex reaction mechanism in the flame of a fuel-rich region during the combustion of hydrocarbons in the absence of air, mainly consisting of a mixture of amorphous carbon and organic matter.Materials and methods. This paper presents the results of a literary review aimed at studying the ways of soot occurrence during the operation of diesel engines, its effect. The mechanical properties of diesel soot are also discussed on the surfaces of friction pairs and engine components.Conclusions. The soot content in engine oil will increase sharply in engines with exhaust gas recirculation, which leads to an increase in temperature in the friction zones and viscosity of the lubricant, as well as to the formation of deposits on hot parts. These processes occur due to the discharge in the crankcase space and the intensification of the intake of gases from the combustion chamber. Oil change intervals should be monitored at an increased rate of soot entering the engine oil.Scope of the study / opportunity. This type of study will help determine the causes of soot in a diesel engine, understand the consequences of using engine oil contaminated with soot particles.Originality / value.
