A review of the literature concerning the molding of centrifuged concrete products was carried out. The peculiarities of centrifugation of concrete, in particular, the manufacture of centrifuged pipes, have been studied. The main parameters and indices of the quality of concrete and the centrifuged tubes themselves are considered. The traditional mode of forming non-pressure pipes is described. The calculation formulas for the parameters of the centrifugation process and their graphical dependences are given. Based on the calculated data, it is concluded that the traditional modes of shaping of non-pressure pipes are characterized by the rotation speed of the mold from 82 to 300 rpm in the stages of loading and distribution of the concrete mixture. At the sealing stage, the control of the rotation speed of the mold varies over a very wide range and depends largely on the viscosity of the concrete mix and the pressing pressure: from 825 to 4400 rpm for concrete pipes with a diameter of 100 to 300 mm. Modeling the parameters of the molding regime during the centrifugation of ring-shaped products in a laboratory installation at a maximum compaction pressure of p = 2.16 kg/cm2 will allow us to refine the obtained data and study their effect on the variability of the concrete structure

Keywords: centrifugal force, centrifugation parameters, charging speed of the mold, speed distribution of the shape, sealing speed of the mold, pressing pressure, centrifugation time, ring-shaped products

In this article the methods of diagnosing the patient's condition from biologically active points analyzed, special attention is paid to one of the main problems of contact diagnostic methods, namely, the reliability of diagnostics; the preferred method of measurement, associated with the change in the probe oscillation depending on the change in the load characteristics, is the self-oscillation method. The purpose of the research is to identify the load characteristics corresponding to the best diagnostic reliability. To achieve this goal, the maximum deviation of the established self-oscillator’s frequency is determined for various changes in the load characteristics determined by biologically active points. It considered about the influence of the deviation of the established self-oscillator’s frequency on the reliability of the diagnosis. The result showed that the change in capacitance could be more informative than the change in resistance, which is due to the large value of the dynamic range of the frequency variation of the self-oscillator.

Keywords: self-oscillation method, diagnostics on bio-active points, the established self-oscillator’s frequency, oscillatory circuit, dynamic range, reliability of diagnostics

In accordance with the requirements of the legislation of the Russian Federation on the basis of a complex of pros-pecting works, it is necessary to establish the rate of removal of the soil layer. The thickness of the removal of the soil layer is established on the basis of a complex of laboratory studies of soil samples taken from established soil hori-zons. The thickness of the soil horizons is currently determined using stock data based on the characteristic type of soil. However, the thickness of soil horizons in a number of cases on sections characterized by identical soil characteris-tics differ. Thus, in each specific case it is necessary to link the soil sections and boundaries of the selected soil con-tours instrumentally through ecological excavations. High saturation with soil workings can lead to a significant distur-bance of the soil cover of the surveyed area. To solve the above problem, it is proposed to use a unit for studying the power of multicomponent dynamical systems for vertical drilling of soil wells

The article considers the experimental estimation of the heat transfer coefficient in a hybrid immersion cooling system with contact point cooling and dry zones. The change in the heat transfer coefficient is made through a change in the Reynolds number for the flow of the coolant in the immersion cooling system. The experimental investigation is carried out on the basis of a numerical simulation model of the process under study. As a result, the dependences of the thermal resistance of the processor-heat exchanger system on the heat transfer coefficient and on the Reynolds number of the turbulent flow were obtained, and the results with the simulation results were estimated. It is found that, with an increase in the Reynolds number, the heat transfer intensification is weaker than the theoretical one. The refinement coefficients for the case under consideration are found.

In this study, the task is to simulate the cooling system of supercomputers with a heat pump on the reverse Stirling cycle by numerical simulation of heat transfer processes in the object under study. The results of numerical simulation of heat transfer processes in the superheater processor cooling system with a heat pump on the reverse cycle are presented. A numerical model of the heat transfer process was investigated. As a result, the dependencies of the required thermal lift of the heat pump are obtained taking into account the thermal resistance of the system. The first liquid cooling circuit - the cold cylinder of the heat pump and the hot cylinder system - the second liquid cooling circuit, depending on the heat transfer coefficient of the heat pump.

The paper presents the development of a system for detecting the status of control and protection system drives (CPS) of a water-water power reactor by vibration signals using the frequency components method. Results of experimental researches at the "Izhorskiy Plant" PO are given. Spectral analysis is used to isolate the frequency ranges of the CPS diagnostic signal spectra, and to develop diagnostic standards. The work describes formation of reference diagnostic vectors (a set of diagnostic features in the form of a binary code) and their comparison with the current state. The developed standards formed the basis for the system of automatic recognition of the object state. The introduction of such a system will simplify the task of collecting, analyzing, comparing drives data during operation at nuclear power plants, as well as improving methods of testing and diagnosing CPS drives, which should positively affect the reliability and resource of equipment.

The article deals with the problems existing in our country that arise in the construction of buildings and structures using new materials and engineering technologies. As shown by the analysis, one of the most significant problems in this area is the violation of production technologies using new materials. To overcome this situation, it is proposed to set the technological normal at the design stage by developing technological maps that take into account the composition and sequence of operations taking into account the properties of energy-efficient materials in detail. In Donskoy State Technical University (DGTU) is developing an intelligent management system that provides organizational and technological and information integration of the stages of design and production through the creation of a single database of technological maps, volumes of work and resources
