Authors: Shershneva E G 
Published: March 2021

AbstractThe article considers urban concepts of new generation cities based on comparison of their architectural and technological features. Analysis of approaches to the design of modern urban areas allowed to determine the dominant principles of urban planning as a synergy of “Creative + Comfort + Smart + Green”. In this context, the author identifies a group of futuristic cities whose projects are based on the synthesis of technological and architectural innovations and eco-friendliness. The definition “neo-city” is introduced and examples are given that are already being built. Population density, lack of territories and environmental problems are reasons for foundation of neo-cities in South-Eastern countries. It is noted that neo-cities are represented in concepts “city without cars”, “city without cars and skyscrapers”, “energy-saving”, “garbage-free” and “high-tech city”. Architectural appearance of each city has its own innovation. Using of bionics principles in architecture of cities is aimed at creating a comfortable environment. Neo-cities are quite ambitious projects in terms of design and financial and technical characteristics. Risk of their operating is technical failures due to the concentration of technical devices and sensors. It is actualized, that the attractiveness of such cities is determined by a comfortable social infrastructure and effective urban management.

Authors: Shishkin E A 
Published: March 2021

Abstract
The paper considers the asphalt concrete mix compaction process. The behavior of the material being compacted under load is described using the Kelvin-Voigt rheological model consisting of elastic and viscous elements. The interaction process of a vibratory roller with an asphalt concrete mixture is modeled using a single-mass oscillatory system. The model input parameters are the characteristics of the material being compacted and the vibrating equipment. The output parameters are the parameters of the roller vertical movement. As a simulation result, the temperature limits of the different rollers types efficiency are obtained. Also, rational vibration exciter frequency ranges were obtained for different types of rollers.
Study of the Local and Imported Rubber Products Made from Fluoroelastomer
Authors: Romanova N V , Shafigullin L N , Buyatova S G 
Published: March 2021

Abstract
The paper provides the results of the studies of the domestic and imported fluoroelastomer O-rings for cylinders with antifreeze cooling. It revealed that the imported materials were more efficient as they featured better compressive strain properties since they provided the acceptable sealing ability when subjected to antifreezes at elevated temperatures, as compared to the domestic materials. The different properties are explained by significantly different filler components and fluoroelastomer chemistry. The comparative analysis showed that the domestic O-rings had a higher compression set both in the coolant medium and in air. The high compression set and subsequent loss of the sealing effect can be caused by low quality of the rubber and inadequate formulation of the rubber mixture.

Published: March 2021

Abstract
A simulation was performed and a method was developed for determining the kinematic and dynamic characteristics of the elements of a mobile snow mass at the stage of their movement on the surface and at the moment of separation from the roof of cylindrical mesh coverings. The developed method allows us to determine the pressure of the snow mass on the shell, calculate the acceleration of the snow elements of the array at the time of sliding off the roof and calculate the time of separation of snow elements from the surface of the shell. It is possible to calculate the speed and value of the angle at which an element of the snow mass is separated from the roof and falls along a ballistic curve.

Published: March 2021

Abstract
Recently, with the rapid development of fracture mechanics, the range of tasks that it allows to solve is also expanding. The article provides a brief overview of problems with singular stress fields starting from a simple fissure and up to V-shaped elements made of dissimilar materials. It shows that the fissure is a special case of an entire class of problems. The destruction of pipelines, as well as all other structures, occurs through the birth and development of fissures. It means that it is more important to study problems with singular stress fields in the oil and gas industry. The article provides a solution to a general problem from which all known solutions follow in particular cases. But if in the case of a fissure the dimension of all stress intensity coefficients is the same and constant, then in general the dimensions of the KIN are determined by the values of a parameter that depends on the elastic properties of materials, as well as on the crack opening angle. This property of KIN, causes difficulties with calculating of strength. Therefore there is a problem - how to determine the strength conditions of structural elements with such singular points. This problem requires further research in this area.

Modeling of Variable Operating Modes of Water-to-Water Heat Exchangers
Authors: Rafalskaya T A 
Published: March 2021

Abstract
Heat exchangers used in heat supply systems operate in conditions of variable flow rates and temperatures of heat carriers. Existing theories for calculating variable modes of heat exchangers are based on the use of dimensionless constant parameters, regardless of their mode of operation. The use of such theories with a large change in temperature or flow rates of heat carriers in the heat exchanger leads to a significant error. Modeling of various variable operating modes of a counter-flow water-to-water heat exchanger with a change in its heat capacity allowed us to establish patterns of change in the parameters of heat exchangers and to construct a technique available for engineering calculations. This task becomes especially relevant when upon transition to new methods of central and local regulation of heat supply systems. Verification of the developed method was carried out on a heat exchanger model in the ANSYS Fluent package. This method is quite accurate; however, it requires the construction of a calculation model and takes a very long time, which does not allow it to be used for operational control of the operation modes of heat supply systems. Comparison of the calculation results showed a rather high accuracy of the developed methodology for different operating modes of heat ex-changers.
Promising Screw Piles Designs for Construction on Permafrost Soils
Authors: Popov S N , Burenina O N 
Published: March 2021

Abstract
Promising designs of screw piles with improved technical characteristics have been developed, which reduce risk of buckling from soil as a result of influence of tangential forces of frost heave, reduce energy consumption when screwing piles into the soil, and also simplify designs and manufacturing techniques of blades. Usage of cryophobic coatings applied to trunk part placed in the active soil layer is proposed to reduce bulging of piles. Applying anti-friction coatings to the blades, as well as usage of greases filling slots at their edges is proposed to reduce friction when tightening. Strengthening adhesive interaction between pile and soil below active layer can be achieved by applying cryophilic coatings and freezing water in gap between pile shaft and soil. Simplification of pile design is assumed by replacing screw blades with segmented or cable blades.

Published: March 2021

Abstract
This work discusses the development of concrete mix compositions using modifying additives, the study of the rheological and strength properties of compositions for construction 3D printing. Cellulose ether (CE), calcium formate (CF), and redispersible polymer powder (RPP) were studied as modifying additives at different percentages by weight of cement. Compression strength tests have shown the most promising compositions for their further study for rheological parameters. The best strength indicators in the early and late periods of hardening were shown by the composition with the introduction of 2% RPP and the composition with 2% CF. The composition with 2% RPP has an increased density and viscosity and relatively low flowability, and also has a shortened setting time, which makes the use of an RPP additive effective for additive construction methods.

Published: March 2021

Abstract
The present study considers an innovative pressure control system for improving reliability of a hydraulic descaling plant. The pressure control system is based on a metal bellows hydraulic accumulator capable of withstanding high pressures. System installation diagram in the hydraulic descaling plant is shown. Design of the hydraulic accumulator is shown. This design allows effective pressure control in the whole plant due to its features of effective forces distribution on additional elastomerics. The materials that can be used to create elastomerics taking into account the peculiarities of metallurgical shops are shown. Dependencies are obtained which show possibility of reducing stiffness of the metal bellows unit when using additional elastomerics. This reduces the cost of the pressure control system by using the metal bellows unit materials with less stiffness.

Published: March 2021

Abstract
The article considers the energy aspect of compaction process of an asphalt concrete mixture with a smooth drum. The ratios between the compaction work and the material stress-strain state were obtained using the simplest rheological models example. To study the asphalt concrete mixture compaction process, a complex rheological model was adopted. Taking into account the obtained ratios for the simplest rheological bodies, an expression was obtained to determine the compaction specific work of an asphalt concrete mixture with a smooth drum. In the course of the compaction energy analysis, it was found that the compaction work is equal to the sum of irreversible losses for viscous and plastic deformation and the energy required to perform an elastic aftereffect.

Published: March 2021

Abstract
The article presents the results of climate tests of ultrahigh molecular weight polyethylene and a polymer composite material based on it. It is shown that the initial ultrahigh molecular weight polyethylene and a composite based on it undergo aging by the sixth month of exposure in the sharply continental climate of Yakutia. It has been established that ultrahigh molecular weight polyethylene and composites based on it must be modified not only with reinforcing fillers to increase physical-mechanical and tribotechnical parameters, but also with technological fillers that first of all, prevent the development of destructive-oxidative processes during operation in a sharply continental climate.
