To the historical context in the poem "Alguziani" (XV century)
Authors: Tesaev Zelimkhan Adamovich 
Published: September 2022

The purpose of the study is to identify historical information in the text of the Georgian-language poem "Alguziani": the identification of the personalities mentioned in it is carried out, as well as the determination of the time of the events described. This is followed by an analysis of the text, which makes it possible to identify signs in it (terms, personalities, events) indicating a certain historical epoch. Then the events described in the poem are dated by comparing its plot with the real historical picture of the period determined during the study. In the course of a comprehensive analysis, a picture is formed that allows, firstly, to identify a number of the heroes of the poem with real historical figures of the XIV-XV centuries, and secondly, to point out specific socio–political processes reflected in the tendentious presentation and poetic form. For the first time, as a result of the analysis, a hypothesis is put forward that determines the dating of specific incidents (the war with the Kalmyk Khan, the war with the Chechen tsar and other plots) and identifies the personalities of the main characters of the work (Alguz, Amakhuni, Cairo Khan, Bibor, Kurtagon and others). The study allows us to express a reasoned opinion according to which the events described in the poem "Alguziani" describe the processes of the XV century and reflect the confrontation of the Crimean Khanate and the Great Horde, as well as the peoples of the Caucasus involved in it. Thus, regardless of who the author of the poem was, it arouses historical interest and can serve as an appropriate source for researchers.

Published: September 2022

The subject of this study is an analysis of the exhibition practices of the Fedoskin lacquer miniature craft in the post-war period (from 1945 to the early 1970s). The purpose of the article is not just to tell about the exhibitions of Fedoskin lacquer products of the post–war period, but above all to show those important changes that allow us to consider the post–war period as an important stage in the history of the development of the craft and his exhibition activities. Having briefly reviewed the bibliography of the issue and given a description of the exhibitions of the Fedoskino labor artel in the pre-war period (1920s – 1930s), the author analyzes in detail the most remarkable post-war exhibitions of the craft, finding both common features with the previous period and the features of the differences on which the author focuses his attention. Using the method of comparative analysis, as well as historical-systemic and problem-chronological research methods, the author characterizes the various forms of exhibition activity used to exhibit products of the Fedoskinsky lacquer craft both in the post-war period and earlier. The scientific novelty of the research consists in the analysis of the activities of museum workers and craft artists in the popularization and public recognition of the products of the Fedoskin lacquer miniature in the post-war period. The main conclusion of the article is the statement of the importance of studying the exhibition practices of the Fedoskinsky fishery of the post-war period for the most complete study of its history and public recognition.
Swing JIB rack stacker crane
Authors: Korytov M. S. , Bezrodina A. E. 
Published: September 2022

Introduction. Rack stacker cranes are the main hoisting and transport machine for maintenance of multi-level rack warehouses. The efficiency and profitability of the warehouse depends on their efficiency. The traditional design of a rack stacker crane includes a trolley that moves along the rails on the floor of a warehouse, a column mounted vertically on the trolley, along which a carriage with a load gripping device and a load rises. The disadvantages of the traditional crane design are the relatively large mass of the trolley, the need to move it along with the column in a horizontal direction when moving around the warehouse, the relatively high energy consumption and the need to strengthen the floor of the warehouse. The crane rail tracks on the floor of the warehouse must be cleared of objects falling from above, which is associated with stopping the operation of the crane and reducing productivity.Materials and Methods. The design of a stacker crane is related to the shape of its working space. In order to improve the stacker crane, its design was developed on the basis of a jib with a counterweight, which does not require rail crane tracks. The crane of the proposed design is capable of storage in the hangars of a semicircular shape. For two warehouses: traditional rectangular and semicircular shapes, a comparative analysis of the sums of geometric distances was performed when the load gripping device moved from the loading point to randomly selected target cells. As a comparison criterion, the sum of the Cartesian distances of the load gripping device movements between the warehouse loading point and the target points, randomly selected according to the law of uniform distribution, was used. Three types of crane operation cycles were studied – simple single, double and mixed.Results. Comparative diagrams of criterion values are given. It has been established that for all types of cycles studied, to the greatest extent when working on a single cycle, the use of a crane of the proposed design with the same storage capacity significantly reduces the total geometric distance that the load gripping device must pass.Discussion and conclusions. Reducing the sum of the geometric distances of movement of the load handling device of the new crane allows to conclude that the time spent on the movements that determine the productivity of the work performed by the crane, as well as the energy costs associated with them, can be significantly reduced. Reducing energy costs is possible by replacing the translational movement of a massive undercarriage with the rotational movement of a balanced jib of a relatively small mass at the crane of the proposed design. Time is not wasted on regular cleaning of the crane tracks, associated with stopping the crane. The number of friction pairs in the proposed design of the crane is reduced compared with the traditional one.
Experimental studies of the uncontrolled shift of the bulldozer
Authors: Troyanovskaya I. P. , Zhakov A. O. 
Published: September 2022

Introduction. External forces from the working body of a road-building machine sometimes lead to its uncontrolled deviation from a given trajectory when performing a technological cycle. In this case, there is a clear dependence of the magnitude of the shift force on its direction. The purpose of experimental studies was to determine the values of the limiting shift force for its various directions.Materials and methods. The experimental tests were carried out on the example of a 10-ton caterpillar bulldozer manufactured by the Chelyabinsk Tractor Plant. The shift was carried out by the action of an external force applied to the edge of the dump in various directions. The external force was recorded on an oscillogram.Results. The shift began with an external force equal to the adhesion limit, provided that the line of action of the external force passed through the center of pressure. The shift begins at much lower values of the external force when the line of action of the external force deviates from the center of pressure. The result of the experiment was the construction of a hodograph of the limiting shift force.Conclusion. The nature of the change in the external force during translational and rotational shear was fundamentally different. It has been experimentally confirmed that the more the direction of the shear force deviates from the center of pressure of the machine, the smaller the value of the external force can lead to an uncontrolled shear.
Effect of electrochemical treatment on substrate adhesion strength in the restoration of motor vehicle parts operating under hydroabrasive wear
Authors: Kotomchin A. N. 
Published: September 2022

Introduction. In the process of chrome plating of car parts, it is necessary to obtain high-quality chrome coatings with specified physical and mechanical properties. Therefore, electrochemical treatment before coating plays a crucial role in the formation of coatings with high contact strength and wear resistance. The study of the electrochemical treatment process will make it possible to develop recommendations for obtaining high-quality coatings when restoring vehicle parts.Materials and methods. To conduct reliable research, the necessary equipment was used, which made it possible to obtain data with the necessary accuracy. Also, modern data processing tools were used to carry out mathematical processing, which excluded the possibility of error and thereby obtain the dependences of factors with the necessary accuracy.Results. When using the developed new chromium plating electrolyte, it became necessary to conduct studies of the modes and time of electrochemical treatment before coating parts made of steels containing chromium and hardened to HRC 55-60 hardness. Based on the results obtained, it was found that the greatest adhesion strength will be when using electrochemical etching with a current density of 130-140 A/dm2 and a holding time of 60-70 s. It is also necessary to activate in the chrome plating solution itself with an anode current density of 70-80 A/dm2 and a time of 30-40 s, with a sharp switch to the chrome plating mode. Conclusions are drawn on the optimization of electrochemical surface treatment before chrome plating, in order to obtain the greatest adhesion to the substrate. Discussion and conclusion. As a result of the conducted studies of the electrochemical processing of the part before chrome plating, it was possible to obtain that when restoring parts operating under waterjet wear, it is necessary to observe the specified conditions for obtaining high-quality coatings with high adhesion strength while maintaining high physical and mechanical properties of the coating.

Studying the effect of multicomponent nano-coating alloy on hydrogen embrittlement of AISI 1018 steel by gas-phase process
Authors: Ali Zainab Z. , Mahdi Baha S. , Althamer Ameen D. 
Published: September 2022

The present study is attempted to investigate the inﬂuence of multicomponent Ni-alloy (BNi-2) on the hydrogen embrittlement (HE) behavior of AISI 1018 steel by using cathodic protection and tensile test. The results show that the HE indexes (HEI) decrease notably when AISI 1018 steel is coated with BNi-2 alloy by DC sputtering process. This coating processes leads to decrease in HE susceptibility of the AISI 1018 steel, which can be rationalized to the enhancement in corrosion resistance and the decrease in hydrogen absorption of the AISI 1018 steel after coating. The tensile strengths of bared samples were decreased with increasing charging time until 24 hours when stable at values 350 MPa. while the coated samples showed an increasement in the tensile strength from 570 MPa to 750 MPa. stabilization in strength at value of 600 MPa was observed after exceeding 48 hours. Also, the tensile test for uncoated specimens indicated a clear reduction on the modulus of elasticity compared with other coated ones.
