Authors: Khinikadze T. A. , Rybak A. T. , Popikov P. I.
Published: April 2021

Introduction. Currently, Russia has adopted a course towards the creation of intelligent machines and equipment. The same holds for mobile technological machines for road construction and public utilities. Therefore, the design and creation of this type of actuators with a self-adaptation function is a critical task.

Materials and Methods. A device equipped with a hydraulic drive with self-adaptation to load and coordination of kinematic and power parameters of the principal motion and the feed movement of the working body of the rock- drilling rig, is presented. To study and design the device based on the mathematical modeling methods of a hydraulic drive and adaptive systems, a mathematical model is proposed. It is developed using the foundations of the theory of volumetric stiffness of hydraulic systems. This enables to accurately describe the impact of the dynamic properties of the hydraulic system (compressibility of the working fluid, elastic properties of pipelines, high-pressure hoses, hydraulic apparatuses) on the dynamic properties of the system as a whole.

Results. The mathematical model for a device with self-adaptation includes submodels of adaptive communication, interrelations of power, kinematic and process parameters of rock drilling, as well as mathematical description of the movement of system elements. The solution to the developed mathematical model was performed in the software environment for dynamic modeling of technical systems SimInTech. As a result, general dependences of the adaptive system on the design parameters of the system and the operating conditions are obtained.

Discussion and Conclusion. The mathematical model of the presented device shows the fundamental possibility of implementing the principle of self-adaptation in terms of load under external and internal disturbing actions during operation. The results obtained can be used under designing adaptive systems of other technological equipment, for example, for the implementation of deep drilling in workpieces with variable properties in its depth.

Authors: Koleda E. V. , Kireev S. O. , Korchagina M. V. , Efimov A. V. , Sperling J.
Published: April 2021

Introduction. The relevance of the presented paper is due to the widespread use of plunger pumps in industrial practice, in particular, in gas and oil production. The quality of working operations and the efficiency of further well operation depend largely on their reliability. The improvement of plunger pumps involves increasing their reliability, increasing their service life, efficiency, downsizing, reduction in weight, labor intensity of installation and repair work. The modernization of the mechanism includes its power study since the found forces are used for subsequent strength calculations. Before the appearance of programs for the numerical analysis of solid objects, the analytical solution to the problem of strength calculation of the high-pressure pump drive frame was a very time-consuming and expensive procedure. The situation has changed with the development of computer technologies and the inclusion of the finite element method in the computer-aided design systems. The objective of this work is to perform a strength calculationon the TWS 600 plunger pump body made of 09G2S steel.

Materials and Methods. A method for determining the reactions of the crank shaft supports of a high-pressure plunger pump and strength calculation of the drive part housing is developed. The direction and magnitude of the resulting forces and reactions of the supports are determined graphically according to the superposition principle of the force action on the supports. Strength calculations were performed using the finite element method in the computer-aided design system Solid Works Simulation. In this case, solid and finite-element models of the body with imposed boundary conditions were used, which were identified during the analysis of the design and the calculation of the forces arising under the pump operation.

Results. The reactions in the crankshaft supports are described with account for the forces generated by the plunger depending on its operating mode and the crank position. The forces acting on each of the plungers and the resulting reactions in each of the supports are determined. The diagrams of stresses and the safety factor are presented, which provide assessing the strength of the body and developing recommendations for creating a more rational design.

Discussion and Conclusions. As a result of the calculations, we have identified areas of the structure with minimum safety factors, and areas that are several times higher than the recommended values. This provides optimizing the designunder study through strengthening the first and reducing the thickness of the metal on the second. From the point of view of weight and size characteristics and maintainability, the results of the strength calculation performed can be used to optimize the design of the pump body under typical operating conditions.

Authors: Berezhnoy S. B. , Kurapov G. V.
Published: April 2021

Introduction. The power analysis of a chain transmission with a toothed chain and involute sprockets considers the centrifugal forces and the friction coefficients between the plate and the sprocket tooth. The work objectives are to determine all meshing forces, and to calculate the coupling coefficient of the gear chain with the involute sprocket in the drive gears.

Materials and Methods. When evaluating the traction capacity of a chain transmission, such parameters as the power analysis and the coupling coefficient of the gear chain with the sprocket are important (it shows what fold the pressure on a given tooth is greater than the pressure perceived by the tooth in front). In the presented paper, the following diagrams are visualized: the arrangement of the plates in gearing with the involute sprocket teeth and the meshing forces. The factors that affect the involute profile of the sprocket tooth are considered. This includes the weight of the chain plate package and the force: centrifugal, friction, normal pressure and tension. At the same time, changes in the coupling coefficient for the subsequent teeth involved in traction are taken into account. The balance of the links i and i

+ 1 of the gear chain is studied in the coordinate system XOY with the center on the axis of rotation of the involute sprocket. The method enables to determine all the desired forces through the geometric calculation of the values of the angular transmission parameters. Using the equations obtained, the following parameters are specified: the coupling coefficient Bi, the tension of the driving branch S1 and the slack branch S2.

Results. A patented transmission stand with a gear chain and involute sprockets is presented. The tests carried out on it validated the study results of a chain transmission with a toothed gear and involute sprockets with the specified parameters. The correctness of the power analysis of the transmission with account for the centrifugal forces and the friction coefficients of the plates and the sprocket teeth was proved.

Discussion and Conclusions. It is noted that the centrifugal forces and the friction coefficients during engagement affect significantly the traction capacity of a transmission with a toothed chain and involute sprockets. The data obtained can be used to accurately estimate the traction capacity of such gears.

The article is devoted to the study of modern opportunities for creating relationships. More and more people use digital means of communication to establish and maintain a romantic connection with people who were previously unavailable due to different cases. However, can we safely say thet digital communication guarantees the possibility of meeting, if people have certain concerns about themselves and others? By these concerns, we mean the theory of attachment. The purpose of our work was to describe current trends in the use of digital dating apps, as well as to explore through the lens of attachment theory the correlation between attachment style and people's choice in favor of online communication.

Authors:   Don State Technical University, Manzhilevskaya S.E
Published: April 2021

The article analyzes the approach to assessing environmental safety in the construction industry. Lack of attention or neglect of the problem of ensuring environmental safety leads to the fact that decisions in this area will be determined by ideas about the potential environmental risk from construction production without taking into account a balanced assessment of the benefits and dangers of this activity. The article provides the basic principles of environmental safety, which must be followed when implementing construction production.

Authors:   Don State Technical University, Belozerov V.V. , Sukhova Y.V. , Belozerov M.V.
Published: April 2021

The article, based on a statistical analysis of fires in the residential sector in southern Russia, presents the results of long-term studies of the "intellectualization" of household electrical appliances (televisions, refrigerators, electricity meters, etc.), which can reduce the number of fires and the consequences of them. It is shown that split systems that “pump through” the air of the rooms where they are installed, as the most “fast” aspiration fire alarm systems do, are the most “suitable” electrical appliances, the intellectualization of which will allow not only early detection of dangerous fire factors and explosion from leakage of domestic gas, but suppress ignition and prevent an explosion if instead of a fan of the indoor unit, a thermomagnetic air separator is installed, which releases oxygen from the air and leads it out through the drainage pipe, and returns the remaining inert atmospheric gases to the room. A model of such a multi-split system was investigated and the modernization of the proposed method with the help of a "magnetic refrigerator" was developed, which will not only double the efficiency of creating comfortable living conditions and reduce energy consumption, but also eliminate fire hazardous external blocks that "spoil the facades" of multi-storey residential buildings
