The method for determining the rational parameters of the kinematics of the suspension systems for high-speed tracked vehicles
Authors: Cipilev A. A , Sarach E. B
Published: April 2022

The requirements for the suspension systems of modern high-speed tracked vehicles impose many limitations, forcing the designer to find unconventional structural and layout solutions. The trend of increasing the power-to-weight ratio of modern and advanced tracked vehicles, in turn, leads to an increase in the thermal load on the dampers, which results in the need to use a forced cooling system, which, together with the requirements for compactness of the chassis units, further reduces the available space for the suspension components. This makes it necessary to find such design parameters of the kinematics of the suspension system, which would ensure that all the requirements are met, taking into account the existing dimensional constraints. The method of choosing such design parameters is presented in this article. This method allows, using the geometric dimensions determining the mutual position of the chassis units on the machine, to find a rational arrangement of the space in the body of the high-speed caterpillar machine elements of the suspension system. This makes it possible to parametrize the kinematics of the suspension assembly for typical structural schemes for securing the pneumatic hydraulic springs (PHS) on the body of the machine, that means it makes it possible to analytically determine the rational distribution of the PHS to provide the most favorable power and kinematic transfer ratio at the design stage. The dependencies given in the article make it possible to assess the feasibility of implementing a particular kinematics, and also give an idea of the conditions that determine the most rational kinematic and power ratio to ensure the minimum dimensions of the PHS and the favorable form of the characteristic of the elastic element.

Published: April 2022

Hydrostatic steering is widespread in the construction of modern tractors. In recent years, it began to apply in designs of haulage trucks and high-speed crawler vehicles. This steering allows for the free arrangement of its main units, simplifies the design, reduces the material consumption of the machine and improves the working conditions of the driver. At the same time, the cost of manufacturing a hydrostatic power steering in recent years has significantly decreased due to the development of high technologies for the manufacture of its units. Hydrostatic steering is a purely hydraulic transmission with flexible connecting pipelines (hoses) of relatively high pressure, less reliable in operation than mechanical tractions, this requires increased attention to the reliability and safety of its operation. For this reason, it is not recommended for use on vehicles with transport speeds above 50 ... 60 km / h. In the known scientific literature there are practically no publications on methods for designing and calculating hydrostatic steering. In the educational literature on tractors, published by professors of the Moscow Polytechnic University, information is given on the design and methods for designing and calculating hydrostatic steering. The task of designing and calculating such a steering is selecting the necessary parameters for the hydraulic cylinder, the metering pump and the power source (drive pump) for it. These units are produced serially, from which the hydrostatic steering is designed. The technique of design and calculation of single-circuit and dual-circuit hydrostatic steering is considered. Information is provided on the characteristics of gerotor type metering pumps of foreign and domestic production.

Published: April 2022

The paper is devoted to the issues of design and improvement of vehicles with hybrid power units, which are intensively developing fuel saving and environment pollution reduction technology for automobile transport. The ideology of hybrid power plants lies in optimal or rational choice of engines operating mode and the efficient use of produced energy. Vehicles with hybrid power plants can be quite effective in saving fuel resources, implementation of modern energy efficiency requirements and improvement the local environment in case of their mass use. The description of the design, functionality and characteristics of two experimental vehicles with hybrid power plants are shown. The design and engineering solutions that allow to extend the functionality of hybrid power unit and to improve consumer performance of vehicles are shown. One of design solutions is proposed by the authors circuit liquid cooling system of reversible electrical machines combined with the internal combustion engine cooling system. Since the power characteristic of some electric motors is not significantly different from the power characteristics of the internal combustion engines, authors believe that to develop automobile hybrid power plant it is advisable to design a two-stage connecting - transforming device, installed in the unit with the reversible electric machines on the basis of patent description at the request of the authors of the invention. In addition, to expand the scope of implementation of automobiles with hybrid power plants and to ensure universality of application, due to specific road and climate conditions of Russia, the authors of this article proposed a concept of extended functionality for vehicle with a hybrid power plant, where two electrical machines having individual kinematic connection with the corresponding wheel of drive axle are mounted in drivetrain. For the concept of such a vehicle with a hybrid power plant authors issued a patent for the invention.

Authors: Kravets V. N , Musarskiy R. A , Volkov S. A
Published: April 2022

The object of the study are passenger automobiles of D, E and F classes according to the European classification, manufactured in 2010-2015 at more than 80 enterprises in all the automotive countries of the world. The purpose of the study is to establish the dependencies of the curb and fully loaded weight of passenger cars on their main classification parameter - overall length. The novelty of the work is that models of modern automobiles were investigated, whereas similar studies were performed on automobiles that were mastered in production at the beginning of the 21st century, most of which have now been withdrawn from production. The performed work is actual, since its results make it possible to scientifically and reasonably choose the most important design parameters of passenger cars: curb and fully loaded weight. Based on the statistical processing of the initial data, analytical and graphical dependencies of the curb and fully loaded weight of automobiles on their overall length in each class were obtained and, in addition, in classes D and E, these dependences were established separately for automobiles with sedan, hatchback, coupe and cabriolet bodies. A total number of 1165 automobile models were analyzed. A large volume of the investigated models allowed to obtain statistically reliable results. The article shows that, with an error of 6.8% to 27.9%, the relationship between the masses and the overall length of cars of all the studied classes can be approximated by polynomials of the second order. The results of the research are recommended to be used in the design and research organizations of automobile concerns for a reasoned selection of the design parameters of the designed automobiles.

Published: April 2022

Currently Bauman Moscow State Technical University, PJSC "KAMAZ" and Moscow Polytechnic University are working on the creation of an articulated-cross-country vehicle on the basis of serial units and aggregates of KAMAZ vehicles, the main design feature of which is the joint junction. Depending on the design, single-stage, two-stage and three-stage hinges are distinguished, allowing to realize rotation around the vertical, longitudinal and transverse axis of the junction joint. The article deals with the influence of the angle of inclination of the pivot pin (vertical axis) and the introduction of an additional (longitudinal) degree of freedom in a single-junction joint at the stabilizing moment. For this purpose, a mathematical model of an articulated cross-country vehicle was developed in the environment of the automated analysis of the dynamics of systems of bodies. The description of the main nodes, systems and control algorithms of the developed all-terrain vehicle is given. During the simulation, the movement of the vehicle was investigated when performing the typical maneuver with different versions of the joint unit with simultaneous registration of the folding angle of the frame sections. Based on the studies performed and analysis of their results, the following conclusions are formulated: the stabilizing moment, sufficient to return the frame sections to the initial position, arises only at large angles of inclination of the pivot pin, and the introduction of an additional degree of freedom in the junction node substantially reduces the stabilizing moment. Further development of the mathematical model will allow at the design stage to estimate such operational indicators of the all-terrain vehicle being developed as smooth running, profile cross-country, traction and braking dynamics under different road conditions.

The comparison of its values with the results of processing of experimental digital oscillograms of test bench masses oscillations showed sufficient for the solution of engineering problems convergence of results.
Perspectives of using humidification subsystems for air conditioning in transport
Authors: Merkulov V. I , Popov A. A
Published: April 2022

With long-term human activity, many factors begin to make a significant influence on fatigue and reduced concentration. The question is even more urgent when it comes to drivers and operators of road construction and agricultural machinery. Work on these modes of transport involves increased danger and additional responsibility for life and health of people. Along with such parameters as ergonomics and optimization of the work and rest regime, the optimal values of the microclimate parameters in the driver's area or the operator of transport equipment play an important role. The microclimate parameters include: pressure, oxygen concentration in air, temperature and humidity. And if there is no need to regulate the oxygen content and pressure in land transport, in contrast to aircraft, and the temperature is regulated by the air conditioning systems of the car, the humidity parameters are not given proper attention. In the conditions of road transport and construction equipment, in areas of low humidity or increased dust generation, a low level of moisture content in conditioned air begins to play a key role in the increased fatigue and the development of drivers chronic diseases. This can be fraught with both a decline in efficiency and economic losses, and the creation of additional dangerous situations for life and health of people. The article discusses and compares the main methods of moisture saturation of dry air, and assesses the acceptability of their implementation in road transport, and conducts typical estimated calculations of changes in system parameters from load conditions. The peculiarities of the application of air humidification in air conditioning systems for ground and air transport are given, a generalized assessment of the methods of moistening, their advantages and disadvantages is made, the most optimal methods of humidifying air are revealed from the point of view of transport technology. For the calculations, the software complex MathCAD was used.
The use of hydraulic communication channel in technical systems
Authors: Trukhanov K. A
Published: April 2022

When developing technological systems, it becomes necessary to transmit information over significant distances without the use of traditional means of communication, because they can not be used, for example, in the field of geonavigation when drilling inclined / horizontal wells. One of the possible channels for transmitting information in this area is the hydraulic communication channel (HCC). Therefore, at present, the task of developing an effective method and approach for transmitting information on the HCC becomes urgent. The purpose of this work was to create a mathematical model of the HCC to provide practical recommendations when used in technology to assess the possibility of transmitting information on it without conducting costly field tests. The article presents a mathematical model of the HCC, which is a long hydroline, taking into account the boundary conditions at its input and output from it. The input boundary condition is represented by a piston pump with a crank-and-rod drive mechanism. The output boundary condition is represented by a throttle - a mechanical device capable of overlapping the pass channel in the hydrolysis line, thereby creating pressure pulses through which useful transmitted information is generated over the HCC. The obtained characteristic for the relative instantaneous feed Q is shown as a function of the angle φ of rotation of the pump shaft. A relation is given that establishes the relationship between the area of the opened throttle windows and the angle of rotation of its shaft. Two applied methods for encoding information in technological systems for information transmission are considered and a dependence for the attenuation of the signal amplitude during data transmission over the HCC is given. A mathematical simulation of the system with HCC and the described boundary conditions is performed. The form of the pressure pulse is obtained. Based on the results of the work, conclusions were drawn.

Czech political Panslavism and ideas of the All-Slavic in the first half of the 19 th century
Authors: Frantsuzova O. A.
Published: April 2022

Originating as cultural panslavism in the Czech-Slovak environment, the idea of integration and political unity of the Slavs became widespread in the Czech political thought of the first half of the 19th century. The defeat of the Polish uprising in 1830 in lands that were part of Russia seriously shook Czech Russophilia and dealt a blow to the positive assessment of the monarchical form of government in Russia, but did not turn away Czech public figures from the ideas of Slavic solidarity. The majority of Czech society, loyal to the Austrian Government, moved to the position of Austroslavism. Ideas about political unification of the Slavs were expressed by Czech radicals, which held Pan-Slavic Congress in Prague in 1848.
