  • Adaptive Discrete Models of Functionally Represented Object Shapes 
    Choporov, S.V. (Проблеми машинобудування, 2018)
    In this paper, a method is proposed for constructing adaptive discrete models of object shapes represented functionally. This method uses an estimate of the accuracy of the finite element analysis to determine the areas ...
  • Analytical Method of Profiling Axial-Radial Compressor Impellers 
    Rusanov, A.V.; Rusanov, R.A.; Pashchenko, N.V.; Chuhai, M.O. (Проблеми машинобудування, 2018)
    A new analytical method for constructing axial-radial compressor impellers with compound lean leading and trailing edges is proposed allowing us to describe a wide class of flow paths based on a limited (small) number of ...
  • Basic Operation Principles and Control Algorithm for a High-pressure Membrane-less Electrolyser 
    Solovei, V.V.; Kotenko, A.L.; Vorobiova, I.O.; Shevchenko, A.A.; Zipunnikov, M.M. (Проблеми машинобудування, 2018)
    A technology of the cyclic generation of hydrogen and high-pressure oxygen, implemented in a single-module and multi-module electrolysis installation, is considered. A schematic operation diagram for implementing the method ...
  • Major Stress-Strain State of Double Support Multilayer Beams Under Concentrated Load. Part 1. Model Construction 
    Kovalchuk, S.B.; Gorik, A.V. (Проблеми машинобудування, 2018)
    The purpose of this paper is to design an analytical model for bending double support multilayer beams under concentrated load based on the previously obtained solution of the elasticity theory for a multi-layer cantilever.
  • Modeling Heat and Mass Exchange Processes in Metal-hydride Installations 
    Chorna, N.A.; Hanchyn, V.V. (Проблеми машинобудування, 2018)
    The paper considers the peculiarities of the heat and mass exchange process in a hydrogen-metal system, which takes place in metal-hydride installations. A mathematical model of non-stationary heat and mass exchange processes ...
  • Peculiarities of Identifying a Power-generating Single-shaft GTE Mathematical Model 
    Lyutikov, A.L. (Проблеми машинобудування, 2018)
    The article proposes an approach to identifying a non-linear unit mathematical model (MM), with a detailed calculation of a turbine flow path to the level of blade rows on the D045 engine bench test results. It describes ...
  • Stress Concentration in Vertical Tank Weld Seams 
    Uspenskiy, B.V.; Buganova, S.N.; Suleymenov, U.S.; Avramov, K.V. (Проблеми машинобудування, 2018)
    The article describes a new method for analyzing and predicting the stress concentration coefficient in a rolled vertical tank weld seam under hydrostatic loading.
  • Stressed State in a Finite Cylinder with a Circular Crack at Non-stationary Torsion 
    Demydov, O.V.; Popov, V.H. (Проблеми машинобудування, 2018)
    This paper considers a solution to an axially symmetric dynamic problem of determining the stress-state in the vicinity of a circular crack in a finite cylinder. The cylinder lower base is rigidly fixed, and the upper one ...
  • Study of the Stressed State Near the Crack That Initiates at the Inclusion Under Longitudinal Shift Wave Influence 
    Misharin, A.S.; Popov, V.H. (Проблеми машинобудування, 2018)
    The purpose of this paper is to study the stress state near the crack that initiates at the inclusion when subjected to a longitudinal shear wave. The formulated problem is reduced to a system of singular integro-differential ...
  • Vibration Features of Titanium Alloy Blades with Erosive Damages 
    Vorobiov, Yu.S.; Ovcharova, N.Yu.; Olkhovskyi, A.S.; Makhnenko, O.V.; Torop, V.M.; Hopkalo, O.Ye. (Проблеми машинобудування, 2018)
    This paper deals with erosive damage influence on the vibration features of the working blades of the fifth-stage of the low pressure cylinder (LPC) of a K-1000-60/3000 steam turbine for a nuclear power plant (NPP). The ...
