In the article we examined the origin of the name of the dome and its connection with the sunny surface of a yurt. The new design of the dome surface is also shown. In this study, using a graphical model of the biquadrate transformation, each point of the transformed line, i.e. n of the prototype, is transformed into points forming a cross-section of the dome surface, while the transformed line gives a cross-section of the surface of the Sun. Then we rotate this section of the found dome surface relative to the vertical section Oх2and get the desired dome surface. When designing a removable dome surface, the format and dimensions of the section are set in accordance with the preliminary requirements. Thus, the biquadrate transformation method that we propose when designing a section of a domed surface, that is, a project of a domed curved surface, is practical and simple for designers. The proposed method in its simplicity is designed to solve various similar curved surfaces and engineering problems.

For stepless regulation of the operating speed of technological machines, in the ranges provided by the technology, it is recommended to use a V-belt variator. However, currently having V-belt variators with a special V-belt have significant disadvantages that reduce their effectiveness. In this regard, a V-belt variator with a standard drive V-belt is proposed, the driven pulley of which is divided into identical sectors, the diameter of the driven pulley is changed by synchronous movement of these sectors in radial directions. Studying a V-belt variator with a standard V-belt drive and a multi-sector driven pulley, the main parameters such as the number of sectors, the traction capacity of a multi-sector pulley, the diameters of a multi-sector pulley, the force of normal belt pressure on a multi-sector pulley, which are necessary when designing a variator, were determined.

Nowadays the hydraulic excavator is one of the leading multifunctional machines that are operated for multi-purpose goals and are also finding increasing use due to the widespread use of replaceable working bodies and working equipment. It is important to note that the use of a wide range of replaceable working equipment and working bodies of excavators not only increases the productivity of machines, but also the level of mechanization of work. The possibility of easy replacement of nozzles increases efficiency and minimizes the likelihood of damage or wear of equipment associated with manual replacement of nozzles. Besides, this will reduce the time for replacing the working body and speed up the work process.This article analyzes and reviews research: publications, patents; also provides an assessment of the quality of the proposed solutions for quick fastening systems on hydraulic excavators.

It is known that in accordance with the rapid development of the industrial industry in the XX-XXI centuries, the use of oil and gas products has increased dramatically. This factor, in turn, has led to problems such as environmental pollution, changes in global temperatures, and a shortage of oil resources. For these reasons, car companies have begun to conduct research in order to introduce hybrid technologies into everyday life. The article examines the history of the emergence of hybrid technologies, as well as the principles and fundamentals of their functioning, as well as an overview of the technologies used at the present stage. The article is based on research concerning the manufacturing technologies of existing commercial vehicles, such as Toyota Prius, Astrolab, as well as fuel and raw materials used in hybrid cars. The article presents the pros and cons of the technologies considered, conclusions that hybrid cars will become an alternative to gasoline and diesel cars in the future.

The article presents the results of research of different fibers on the effect of strength characteristics of fine-grained concrete. The basic characteristics of the types of fibers used for the manufacture of fiber concrete are given. The results of laboratory research of polypropylene and basalt fibers for dispersion reinforcement of concrete are given. To estimate the strength changes the samples were made and tested in compression at the age of 3, 14 and 28 days of normal-moist hardening. The results of determining the compressive strength of fine-grained fiber concrete without adding fiber (control composition) and with the addition of polypropylene fiber 0.1, 0.5, 1.5, 2.5% of the mass of cement and basalt fiber 0.05, 0.1, 0.2, 0.5% of the mass of cement are given. It is shown that the most optimal limits of the introduction of polypropylene fiber in the mixture can be considered 0.5% of the weight of cement, which leads to an increase in compressive strength up to 9.09%, compared with the control composition. The introduction of basalt fiber in the mixture of fine-grained concrete in an amount of 0.1% of the weight of cement can increase the compressive strength by 11.4%.

The purpose of this research was to assess the feasibility of constructing high-performance paving (Superpave) for Kazakhstan with only locally sourced ingredients. Similarly, a standard Marshall technique combination that meets the technical requirements of Kazakhstan was compared. One granite aggregate supplier, 2 aggregate grading, and 2 types of asphalt binder made up the test design. Consensus and source aggregate characteristics requirements met with the Superpave design mix method using locally manufactured granite aggregate. Also, the mixtures volumetric parameters indicated that the asphalt binder content of the superpave combination has shown lower than locally-traditionally Marshall mix. The combinations of Superpave fared better in rutting and moisture resistance tests than those made in the conventional manner. After the ITS values from both samples were averaged, the decrease in significance for the superpave mixtures was 9.1%. It was below the 20% loss level required by the Superpave guidelines. Also by rutting resistance results were significantly differences for 85.5% PG70 with 9.5mm NMAS. All of these results point to the superiority of new method Superpave over the Marshall method.

This paper discusses the anisotropic properties of soils and the issue of the influence of soil wetness on the stress-strain state of an anisotropic foundation. The study of material properties and the nature of these properties is directly related to the origin and structure of the object under study. The most important of them from the point of view of calculations of foundations, design of buildings, and structures are deformation, strength, and filtration anisotropy, which introduce changes to a greater or lesser extent in the stress-strain state of soil massifs. The entire set of physical and mathematical properties of soils is determined by their structure and texture, which, in turn, are formed depending on the composition and genesis of soil deposits, as well as under the influence of external factors leading to the transformation of the stress state of the soil mass. Practically in all experiments in which the deformation, filtration, strength, and other properties of soils were studied in various directions, a difference in their indicators was noted. Such results testify to the anisotropic manifestation of these properties. An elastic (linearly deformable) soil model is considered a design model of soils that make up an anisotropic base.

Currently, the prediction of electrical loads is an important task. On the basis of forecasts, the operating modes of stations, the network configuration are calculated, the efficiency and quality of electric power is estimated, the schedule of repair work is calculated, etc. The electric load forecasting model is one of the foresight tools for making management decisions when managing electric power systems. This article consists in the construction, evaluation and comparative study of various models for forecasting electricity consumption. The following approaches and methods in forecasting were studied and analyzed: neural network, neuro fuzzy.
