Compensation of temperature errors in pressure piezoconverters
Authors: Emets S V , Khoroshavina E A 
Published: November 2019

Abstract
Measuring pressure converters are one of the most popular control devices in technological processes. The most additional common error is temperature error. One of the causes of the additional temperature error is the uneven temperature field on the pressure converter measuring membrane surface that is determined by the nature of temperature impact. Constructive methods for reducing the stated error lie also in finding the topology of a resistance strain gage on the converter membrane that ensures minimum sensitivity to the uneven temperature field while retaining the pressure sensitivity. The effectiveness check of various topologies is hindered by different technical, technological and economic problems. The article proposes to run a check of topological solutions with the help of a mathematical model of the membrane temperature field that takes into account the temperature impact on the converter. The exponential function was chosen as a modelling function because it corresponded to the experimentally obtained temperature distribution data. This function allows virtually forming temperature field distributions on the membrane surface, characteristic of static, dynamic (thermal shock) and targeted temperature impact. This model will allow assessing without a physical experiment of additional temperature errors of various topological solutions. Additional temperature errors of the classic four resistance element topology and the topology proposed by the authors with component resistance strain gages are analysed as examples. The potential of topological solutions in minimization of additional temperature errors in pressure converters is shown. The approach set forth in the article streamlines the search for constructive solutions for minimizing additional temperature errors in pressure converters by reducing physical simulation stage.
Methods for removing uncertainty in multi-criteria problems of effectiveness evaluation of decision-making
Authors: Moiseev V V , Terentyev A V , Rogov V R , Karelina E A 
Published: November 2019

Abstract
A scientific approach to methods of technical support, economic and organizational management, as well as planning the activities of enterprises often dictates the need to make decisions not on one but on several performance indicators simultaneously. The presence of a number of situations with one or another degree of uncertainty in modern difficult conditions of forecasting requires the involvement of a certain mathematical apparatus for its description. The task of removing uncertainty is becoming complicated if it is necessary to evaluate the effectiveness of control actions in the system according to several performance criteria. Therefore, at present, the development of mathematical methods is actively underway, which allows solving applied problems in a multi-criterial formulation. The article describes the approach to solving multi-criteria problems based on the principle of observing the hierarchical ratio of probabilities of possible states of the external environment of the study.

This article presents an imitational-dynamic model for calculating the reproductive effect of amortization of fixed production assets with various accrual methods. The model was developed on the basis of the system dynamics method using Powersim Studio tools. In the model, calculations were carried out for five amortization methods: linear; arithmetic-digressive (declining balance method); geometrically digressive; progressive and method of writing off the cost of the survival year sum. The model was used as a tool to study the impact of various amortization methods on the dynamics of its reproductive effect. As a result of experiments with variants, the most effective method was determined. The conducted study allows concluding that the constructed imitational-dynamic model is quite universal and on its basis, it is possible to conduct a variety of studies concerning various issues related to amortization deductions.

Authors: Lyamzin O L 
Published: November 2019

Abstract
The formation of national economic clusters, considered today as one of the important ways to promote the economic growth and intensification requires not only the expressed interest of the subjects of clustering (top management of companies, territorial administrations, etc.). It is also important here is the degree of applicability of the conceptual and instrumental base of these processes for the Russian conditions. Data collection, its grouping, analysis, and further use in cluster management should be based on the logic, which is reasonable and transparent for managers. This logic should organically include the specifics of the interrelations within the system of indicators of the state of clusters, and then - the essence of the estimates formed on this basis. The proposed article is devoted to the reflection of the author view on the solution of these issues.

Published: November 2019

Abstract
The task is to design an instrument of interaction for an operator and a cyber and physical system in the Industry 4.0 production. There are three main technological operations defined which are necessary for the production operator interaction with the cyber and physical system. Those technological operations are: control (programming), exploitation (condition monitoring) of cyber and physical systems and its servicing (maintenance and materials and components refilling which are necessary for item manufacturing). Components and their application order with the interaction scheme are defined which are necessary for an operator to control and exploit a cyber and physical system. Those components are elements of the Humane-to-Machine technology. Cyber and physical system technical servicing technological operation is proposed to be conducted with a special machine and program device — helmets which support digital technologies of augmented reality. There is a description of a functionality principle for an augmented reality helmet.

Published: November 2019

Abstract
The article describes the theoretical study of the noise generation parameters under friction of a base cylinder of a rotary-screw mover. The analysis of the influence of parameters of the base cylinder (diameter, angle of winding of the helical blade, length) and the vehicle motion parameters (speed, mass) on the noise level arising from mover interaction with a single obstacle is presented in the paper. The conditions for the occurrence of sound vibrations are shown. Analysis of the research results allows us to conclude that a significant noise level generated by the rotary-screw mover can take place only when the vehicle is moving on ice. The created model and the obtained results can be applied by developers of all-terrain vehicles.
Hierarchical selection of technological equipment for the production system
Authors: Pishchukhin A M , Akhmedyanova G F 
Published: November 2019

Abstract
In this paper, a study of technical and economic indicators is used in the design and selection of production equipment. Since the indicators currently used are considered independently of each other, they are rarely agreed upon. To overcome this drawback, it is proposed to consider them depending on five levels: parametric, structural, technological, economic and social. This immediately introduces the hierarchical subordination of indicators and their connection with social needs and a rapidly changing economic environment. As an example, a reconfigurable production system is considered, the equipment load factor, which requires increased flexibility from the system, is chosen as the main parameter. The reconfigurable production system, in addition to software or parametric flexibility, allows you to increase it due to the ease of changing the production structure, and when it is not enough, and this can move to reconfigurable production, which provides greater adaptation to changing conditions and expands the range of products produced through the use of transforming machines. The developed approach is applied to the technological system of a regional enterprise. The results, presented in the form of histograms, show a progressive increase in the equipment load factor as it moves along the hierarchical scheme. Thus, to answer the question what equipment should be designed or selected at the operating enterprise, it is necessary to consider five hierarchical levels with their own indicators each. At the same time, the indicators of the lower level can be determined only after the determination of the indicators of the higher level.

Published: November 2019

Abstract
Processes of cutting and movement of potash ore during operation of «Ural-20R» heading-and-winning machines are followed with its breakage leading to the increase of number of non-washable powdered classes (particle size less than 0.25 mm) in the breakage products. The sources analysis of dust-like classes formation during the work of «Ural-20R» machines is performed. The regions of rational (by minimum output of dust-like classes) values of breaking parameters of potassium solid mass in use of checkered and consistent cutting schemes are defined. The analysis of the operating parameters compliance of the planetary-disk operating members of «Ural-20R» machines of various modifications with rational cutting parameters is carried out. Technical proposals on improving the operating members of «Ural-20R» machines by use of the crossed procedure of potassium solid mass breaking are reported. It is proved that the proposed solutions will reduce the number of dust-like classes in the breakage products and reduce the specific energy consumption of the potash ore production processed.

Authors: Makhmudova I F , Karimov D D , Gulin D A , Bykov L I , Gumerov A G , Akhmetov R T 
Published: November 2019

Abstract
During the design and construction of pipelines at the intersection of natural or artificial obstacles, various beam systems are used. They often include a compensator which must collect section elongations composed of temperature extensions from the internal pressure and longitudinal forces caused by longitudinal movements of the underground sections adjacent to the above-ground pipeline. This article analyzes sources that highlight the design of beam crossings with compensators. The design in which the maximum bending moment in the middle of the span and the support moment have equal absolute values is optimal. Based on the identified deficiencies of the design schemes, it was proposed to calculate the length of the single-span beam crossing with compensators using a different scheme.

Authors: Magomedov I A , Orlova I V , Lisichko O I , Alikhadzhiev S Kh 
Published: November 2019

Abstract
This thesis is focused on comparing fast fracture of two screens of smartphones (Apple 5 and Samsung alpha). The analysis is done using the novel method, which is eXtended Finite Element Method (XFEM) and a cohesive element (CE) using software Code_Aster and Salome Meca. An apple screen (Sapphire) illustrated high resistance to fracture, while Samsung (Gorilla Glass) fractured with applied force is smaller than the one applied to Apple (Sapphire). However, Gorilla Glass wins in crack propagation by demonstrating better performance. We worked out that the size of screen also influenced fracture. Gc influence on crack propagation was observed. The results illustrated that by increasing Gc the crack propagation will be reduced and vice versa. In addition Gc change will have more influence when applied force is smaller. Influence of other cracks on initiation new crack was also analysed. The results showed that the initial cracks might increase displacement of deformed body, but reduce crack propagation. The results also showed that Gorilla Glass tends to be deformed more if compared to Sapphire.

Study of changes of vessel’s speed in ice conditions on the Northern Sea Route
Authors: Ol’khovik E 
Published: November 2019

Abstract
Based on archive information of automatic identification system (AIS), studies of changes in the commercial speed of large-capacity ice-class vessels Arc7 along the route in the Kara Sea on the Northern Sea Route are carried out. To plan maritime traffic in the Arctic seas, it is necessary to have objective data on the influence of various factors on speed and time of transition. To ensure the safety of Arctic shipping, it is necessary to have objective data on the effect of ice on speed and maneuverability of vessels. It was proposed to use a geographic information system (GIS), the layers of which include data on the speeds and routes of vessels of various capacities and data on monitoring ice conditions. Detailed attention was paid to the route in the Kara Sea, as it the main entrance to the Northern Sea Route from the west, the movement of vessels was studied during the winter navigation period under the most severe ice conditions (March) and during the summer navigation period for clean water (September). It was found that in the dense stream of ships in summer navigation, the speed of ships varies slightly and depends on the density and intensity of traffic, and in winter navigation, the speed of ships has dramatic changes as ships go along the route with a large lateral deviation from the route. Research is performed at the Arctic Faculty of Admiral Makarov State University of Maritime and Inland Shipping. In future, all obtained relationships can be used for modeling the maritime traffic on the Northern Sea Route with an increase in the number of large-capacity vessels with Arc7 ice-class.
