Published: June 2019

Abstract
An active geological study of promising areas for oil and gas is being conducted in areas where geological signs of associated hydrocarbon manifestations are detected. The development of deposits contributes to a developed system of cracks in the surrounding rocks. Fluid supply to fractured reservoirs occurs through the channels of deep faults. Prolonged winter freezing of rocks inhibits the release of gases into the Earth’s atmosphere. The accumulation of hydrocarbon gases in the near-surface cavities creates risks of gas emissions, fires and explosions. Prediction and rapid diagnosis of gas emissions is based on planetary observations from satellites of ozone concentration in the atmosphere. V.L. Syvorotkin experimentally showed a causal relationship between hydrogen degassing and the formation of “Ozone Holes”. Satellite measurements of ozone concentrations in the atmosphere allow daily monitoring of hydrogen degassing sites from the Earth’s surface. The state of the soil surface in the areas of deep degassing is determined by secondary features. These are griffins, soil emissions, ring-shaped structures of gray soil (falling fertility), and hummocks of specific morphology. Such hummocks are formed as a result of the vital activity of “Hydrogen bacteria” and are markers of gas emission on the ground. In combination, methane with hydrogen is capable of detonation at concentrations ranging from 1%. The danger increases in the presence of iron-containing minerals that can catalyze the oxidation reaction. Preventive measures are proposed to prevent the sudden release of flammable gases: by drilling a network of control waste wells with a depth of 100 to 200 meters. Such wells are similar to ventilation wells in areas of coal mining.

Authors: Zlobina I V 
Published: June 2019

Abstract
Based on the analysis of trends in the development of aviation equipment for various purposes, the expansion of the use in its bearing structures of polymer composite materials, reinforced with carbon fibres with a combined structure containing distributed in the volume of metal honeycomb fillers is shown. This increases the anisotropy of the physical and mechanical properties of such structures of different chemical composition and properties of materials, which makes it difficult to manoeuvre the aircraft due to the different stability of metals and composites to multidirectional dynamic bending and shear loads. It is stated that the problem of increasing the strength characteristics of PCM can be solved by their quasi-structuring in the microwave electromagnetic field, but the influence of this factor on complex structures containing metal regular elements needs further study. Experimental studies of the effect of short-term exposure to microwave electromagnetic field with a frequency of 2450 MHz on the modulus of material elasticity, which is a structure of two plates of carbon fibre with aluminium cellular elements located between them. It was found that compared with the control samples, the samples exposed to microwave electromagnetic field have an increased modulus of elasticity by 31.8%. Limit shear stresses also increase by 29%. Thus, the treatment of formed and cured polymer composite materials with built-in cellular metal structures in the microwave electromagnetic field is possible and allows to perform hardening quasi-structuring of such products and increase their performance parameters.
Kinematics and arrangement of an active sidestick
Authors: Samsonovich S L , Rozhnin N B , Larin A P , Makarin M A 
Published: June 2019

Abstract
The article is about design of the active aircraft control sidestick. The disadvantage of the known frame constructions, apart from the large dimensions, is the difference in the dynamic characteristics of the channels when using the same actuators, because the mass of a frame mounted actuator is the load for a fixed base mounted actuator. As a result the kinematic scheme of an active control sidestick which don’t use a frame is offered. The frameless scheme contains two identical actuators mounted on the fixed base, at that the interference of channels is excluded. The derivation of the actuator’s gear ratio is given. It is shown that this dependence between the rotation angle of the actuator output shaft and the handgrip deflection angle is of a sinusoidal type and that it is close to linear in the range of the handgrip operating angle.

Resource allocation models at resource quantity dependence on demand
Authors: Kalach A V , Rossikhina L V , Govorin E B , Golovkin R B , Shumov P V 
Published: June 2019

Abstract
The paper describes the reverse priority mechanism for a resource allocation problem under the condition when the quantity of resource allocated depends on demand, i.e. on the sum of consumers’ requests. A particular case of the problem for two consumers and a general case for more than two consumers with equal and different priorities are discussed. The linear dependence of the quantity of resource allocated on demand is considered for the particular and general cases. It has been obtained that the use of linear dependence is appropriate in the case with two consumers, when a certain predictable strategy of consumer behavior can be found. For the higher number of consumers, it is feasible to use this dependence, when there is a consumer with a significantly higher priority as compared to the others. Otherwise, the consumers’ behavior becomes hard to predict. The piecewise-constant dependence of the quantity of resource allocated on demand has been studied for the particular and general cases. The overall conclusion has been obtained and has stated that the consumers’ behavior becomes hard to predict, including surges of estimates, when the reverse priority mechanism is used in cases of resource quantity dependence on demand.

Published: June 2019

Abstract
The stress and plastic strain distributions around pyramidal indenter in steel 10 has been investigated by exploring the Vickers hardness of carefully prepared median plane sections through indentations. Experimental results showed that, the maximum strain is observed at a certain depth below the indentation surface inside the hydrostatic compression zone. The minimum permissible ratio between the coating thickness and the indentation depth, which excludes the influence of the substrate on the indentations results obtained by Vickers indenter, is substantiated. The shape and dimensions of plastic deformation zones around Vickers indentations were determined. As a result, between the indentation volume and the deformation zone volume established directly proportional relationship.
Optimization of gear ratio of variable mechanical gearboxes
Authors: Ulanov A G , Troyanovskaya I P 
Published: June 2019

Abstract
The effectiveness of the coordination process of the “engine-transmission” system is largely determined by the functional purpose of the car being designed. The solution to this problem is possible by choosing the optimal transmission parameters. Using a continuously variable transmission will make this process manageable. However, optimization is always performed according to a certain criterion. You can use its dynamic performance and fuel economy as an optimization criterion. The article presents a mathematical model for determining the current gear ratios of a continuously variable transmission of a vehicle depending on its mode of movement. The dependence of the transmission ratio of the vehicle on speed allowed us to find the mode of movement of the car with the minimum acceleration time. The dependence of the transmission ratio of the vehicle on the engine speed allowed us to find the driving mode with minimal fuel consumption. The recommendations received by the authors on the choice of transmission ratios can be used in the design of the control system. Automation of control will allow optimizing the pattern of change in the gear ratio of a continuously variable transmission depending on the mode of movement of the vehicle.

Authors: Vikharev S N 
Published: June 2019

Abstract
The subject of research is the method of vibration calculation of the plate knives. The study of the shapes and frequencies of free oscillations of knives was carried out using the finite element method and analytics. The error between theoretical and experimental studies does not exceed 9%. A diagram is proposed for determining the resonant modes of the plate knives. The proposed measures to reduce oscillations and dynamic stresses of the plate knives are as follows: change of the frequency of the rotor rotation; change of the length of the knives; change of the crossing angle of the rotor and stator knives; the choice of material for knives; use of damping devices in the plate design. The plate with interchangeable working elements and a headset with damping devices of knives are proposed and protected by patents for useful models. The developed method of vibration calculation can be used in other industries, for example, in mining and metallurgical industries.

Abstract
The research subject is the method of dynamic calculation of knife refining machines together with the supporting structure. The design of refiners and supporting structures is carried out by various organizations. The knife refining machine and the supporting structure are a single dynamic system and, therefore, they must be calculated together. The forces exciting the oscillations of the refiners are investigated. Dynamic and mathematical models of the system are developed. The proposed method of dynamic calculation has been successfully tested on TF-52 and TWIN-66 refiners by OJSC “Solikamskbumprom”.

Authors: Naumov V A , Velikanov N L 
Published: June 2019

Abstract
The article presents the results of calculations of characteristics for water-ring pumps. Water-ring pumps are energy-saving and high-performance equipment, often used for pumping explosive gases or when working with flammable environ-ment. The design of water-ring vacuum pumps and compressors of many manufacturers is the same. The disadvantage of this type of compressors is their low overall efficiency. The algorithm and examples of determining the characteristics of compressor machines used in modern vacuum installations are considered. Based on the results of processing of experimental data of Erstevak ELRS models, empirical dependences and power consumption parameters are obtained. The isothermal efficiency of the liquid ring pump over the suction pressure has been normalized. Characteristics of isothermal power and efficiency are built. The dependence of the highest isothermal efficiency of the water ring pump on the performance (pumping speed) is obtained.

Published: June 2019

Abstract
The paper presents the results of electrical and functional testing of 160 experimental samples of solid-state drives with capacities ranging from 256 to 1024 GB, assembled using 4 types of NAND-memory chips. As a result of testing, read and write speeds of SSD were measured in sequential and random modes. The maximum read and write speeds in the sequential mode were 540 and 410 MB/s, and in the random mode, 72000 and 68000 IOPS. When measuring disks of the same type, a relative speed variation was observed, which was significantly greater with write operations (3.7%) than with read operations (0.45%). It was also found that the write and read speeds were limited by the performance of the disk controller.

Published: June 2019

Abstract
A study of single-stage reducers, made in a horizontal pattern, having the same technical characteristics and a similar configuration, but differing in the material hardness of the gear pair parts has been carried out. The design of reducers, the determination of the mass-dimensional parameters of the parts and the entire product assembly was carried out in one of the CAD programs of three-dimensional modelling. For identically designed reducers, a comparison of the mass and dimensions of all the parts was made. The data on the total masses and overall dimensions of the assembly items, as well as the results of the heat treatment time of gear wheels and toothed wheels are given. The parts dimensions of which undergo the greatest changes in size due to the replacement of gear and toothed wheel materials are identified. The paper gives the calculation of the machining time and the calculation of the cost for the production of a batch of 10 thousand pieces per unit of production, taking into account the cost of raw materials and materials, heat treatment, energy and technical needs, wages and social deductions, repair and maintenance of equipment, general production and selling expenses for these parts. As a result, data were obtained about the difference in the cost of production of a batch of reducers under study.

Authors: Sysoev S N , Bakutov A V , Dang H L , Andreev A V 
Published: June 2019

Abstract
The paper is devoted to the research of pneumatic membrane probes containing membrane based rod that runs a function of the hard centre. They are widely used in engineering as shut-off and control apparatus machine, chemical, oil gas and other industries. The influence of the rod support parameters on the stiffness characteristic of the rod stroke from the payload is analysed. The operation methods of membrane drives are considered. The possibility of enhancing their efficiency by using the effective membrane area is shown. The authors applied a method in which the effective area of the membrane is used during the drive operation by adjusting the bending stiffness of the support. A device has been developed in which the support is made in the form of a limiter for the flexural deformation of a membrane and an autonomous elastic shell forming a hermetic chamber connected to an overpressure pneumoline. Field studies of a single-membrane pneumatic drive were carried out on a laboratory setup. Studies have confirmed the industrial applicability and effectiveness of the developed technical solutions. In a drive with a membrane made of IPR-1266 rubber, 1 mm thick, 105 mm in diameter, and a camera with a diameter of 62 mm, its stiffness characteristic significantly increases. Compared with the traditional membrane drive, this characteristic is enhanced by more than three times.
Forecast technique for roller bearing life as random value
Authors: Velikanov V S , Dyorina N V , Panfilova O R , Antropova L I , Zalavina T Y 
Published: June 2019

Abstract
The article deals with the use of the linearization method to take into account the stochastic nature of factors affecting the life of bearings. In addition, we should pay attention to such factors as the degree of contamination and viscosity of the lubricant, as well as the properties of the material from which the bearing parts are made. The developed method allows estimating the degree of influence of these factors on the bearing life. In order to adapt the graphical dependencies to the physic-probabilistic approach, Lagrange interpolation polynomial is used, which allows obtaining the calculated dependencies and automate the resource calculation. The linearization method makes it possible, if necessary, to simplify the mathematical model, neglecting the arguments that have minimal impact on the calculation result.
