  • Design model of a radial bearing with a two-layered porous coating on the surface of a shaft operating on an electrically conductive lubricant

    In the paper, based on the linear equations of motion of an electrically conductive liquid lubricant for the case of a "thin layer", the continuity equation and Darcy, the exact self-similar solution of the problem of hydrodynamic calculation of a radial bearing with an electrically conductive lubricant is given. A field of velocities and pressures in the lubricating and porous layers was found in the work, in the following, analytical dependences were obtained for the main operating characteristics of a bearing with a two-layer porous coating on the shaft surface. An estimate is also given of the effect of the electrically conductive properties of the lubricant, the presence of a porous layer on the main operating characteristics of the bearing.

  • On the stressed state of a thin disk with allowance for the dependence of the yield stress on temperature

    Within the Tresca yield criterion and its associated flow rule, the stress-strain problem in an elastic-plastic thin circular solid disk is considered under a temperature field such as the yield stress of the material depends on the temperature. In the central part of the disk the temperature is homogeneous. On the outer boundary, the disk is subjected to uniformly distributed pressure and constant temperature. The objective of the paper is to determine the service conditions which allow to obtain the temperature in the central part of the disk and its radius such as the initiation of the plastic zone starts either from the center of the disk or from its outer contour. The elastic-plastic boundary is calculated, and the plots for stresses and strains are presented. To verify the solution, the equivalent stresses for permissible plastic regimes are investigated together with the stress vector hodograph . The algorithm of similar problems is developed. The validity of the usage of the Tresca yield criterion when the yield stress of the material depends on the temperature is discussed.

  • Analysis of the stress-strain state of a monolithic concrete fastening for underground structures with non-circular outlines

    Using simulation and finite element method calculations of stress-strain state of monolithic concrete support for underground structures with non-circular outlines made of fast-hardening concrete are carried out in the paper. Based on the obtained results, the maximum stress zones and their magnitude in the reinforced concrete support are established. The stresses are compared with circular-form supports. The factors influencing the stress state of the support are determined.

  • Simulation of the problem of duel three persons

    In general, games like duels, in which each of two players has the goal to eliminate the enemy, are quite a popular problem from game theory. The problem becomes much more complicated when you add players. The term ""truel"" we understand the rivalry three players. They are assigned some values of accuracy the probabilities of eliminating the opponent in one shot. At each stage of the game is chosen by the active player (the selection rule active player either randomly or by prior agreement between the players about their participation). The active player chooses an opponent to eliminate or passes the course. Developed mathematical models for different formulations of the conditions of the game (random or fixed choice of the active player). For each model are analyzed based on the probability of winning in the ""truly"" of accuracy, based on randomly generated program values. Comparing analytical solution and simulation, we see that they have the same answers. For large dimensions similar games analytical method requires complex calculations, so an acceptable alternative is the simulation method. Data research nahegelegenen in political and judicial practices, as well as analytical tools for the study of the theory of evolution.

  • The method of reconstruction of automatic control systems for forest machines

    A method and algorithm for automatic control of forest machine systems under the canopy of the forest is proposed. A method for automated management of information flows of logging processes is developed, based on the created three-dimensional digital spatial models of real forest areas subject to felling. At the same time in the management of machines a system is used that provides synchronization of virtual models with actual data, which will allow full accounting of processes, changes and displacements of extracted wood resources

  • Effect of pre-sowing soakingin water, activated plasma on seed germination of tree species

    The aim is handling trees seed non-thermal plasma activated water and its research results to improve the percentage of seed germination and rapid germination. Water treated plasma, has the ability to activate the germination. This significantly changes the acidity of the environment. Study on the treatment of seeds with non-thermal water plasma was conducted for Scots pine (Pinus sylvestris L.), Norway spruce (Picea abies L.), silver birch (Betula pendula Roth.), ash-leaved Maple (Acer negundo L.). Germination pine seeds soaked in plasma activated water for 2 minutes, increased to 22%, 11% spruce. Such seeds have a short period of germination. The period of germination was reduced to 1 day for birch and maple for 3 days for a total increase of germination by 18 and 16%. Phytopathological analysis identified a certain bactericidal effect. The number of seeds infected with fungi of the genus Alternaria, Penicillium and others decreased. Treatment did not affect the infestation of seeds fungi of the genus Spicaria, Germescium. As a result, there have been major findings and recommendations on the application of plasma activated water for seedbed preparation seed trees.
