COMPACTION OF SATURATED SOILS WITH REGARD TO COMPRESSIBLE PORE FLUID AND SOIL CREEP
Authors: Smolin Yu. P. , Vostrikov K. V. 
Published: October 2019

The paper describes the problem of consolidation of clay soil with spherical tensor and stress deviator, taking into account compressibility of pore fluid and the soil creep. In solving the problem, the differential equation is suggested for compacting cohesive soil filled with linearly compressible groundwater. It is considered that the gas volume in the groundwater does not exceed 10 %. The solution of the differential equation is based on the Fourier transform.For the numerical calculation of creep during compaction of consolidated soil an easy-touse method was used, i.e. testing of soil samples of the same monolith in the compression device, but different height. Knowing the relative vertical deformation of these samples, approximation and extrapolation methods allow to find the relative deformation at the sample height tending to zero. At almost zero sample thickness, deformation depends only on the soil creep, while the pore pressure will no longer play a role.The obtained values of the relative strain are used to select the function of the creep nucleus. It is found that the exponential function optimally describes the process of soil compaction over the entire area: from the beginning of compaction to its termination.Knowing the pressure, the stress in soil and the amount of sediment are found with a triaxial compression, taking into account its instantaneous deformation.

BEST PRACTICE APPROACH FOR WASTEWATER MANAGEMENT IN THE EDIBLE OIL INDUSTRY
Authors: Stepova K. , Derun O. 
Published: October 2019

Abstract. The capacity growth of the edible oil enterprises at the present stage of development leads to the formation of huge amounts of used water, which form the production wastewater. The main pollutants are organic substances, mainly fat. The existing treatment plants are not able to remove them from the water up to the level of sanitary requirements. These pollutants cause the processes of decay, water blooming, infection with pathogenic bacteria and, as a result, adversely affect the fauna and flora. For many enterprises in the industry, proper wastewater treatment is a significant problem. In industry, in order to reduce the amount of water used, and improve the quality and/or quantity of the effluent, it is strongly recommended that a ‘best practice’ approach is adopted, where avoidance of water usage is the most desirable, and disposal of wastewater the least desirable practice. Aim of the study. To propose measures for reducing the impact of edible oil industry on the state of surface wa-ter basing on the Best practice approach. 132 Вісник ЛДУБЖД, №19, 2019 As a result of the studies, the increase of the pollutants content in river water after the wastewater discharge of the edible oil production was revealed. In particular, the content of nitrite, nitrate and ammonium nitrogen, hydrocar-bons, chlorides and sulfates, fats and oils increased; the total iron content increased 10 times. The phosphates, petrole-um products and surfactants were defined.Suggested measures for optimising water efficiency in the edible oil industry include: physical refining, continuous deodorization, cleaning in place, recovery of heat condensates, equipment upgrade, dry clean-up techniques, cooling towers, blowdown wastewater recycling, installation of water meters, education of staff, re-use water, re-use treated effluent.

In the article the influence of binder hardening of concrete processes and changes in the phase composition of cement by heating to 1000 °С. It was established that the presence of active mineral adds in cement composite increases the strength of concrete at ordinary temperatures as well as when heated in a fire.
Damage of structures, accompanied by loss of strength characteristics of concrete under the influence of high temperatures of the fire due to the decomposition of water-containing crystalline hydrates, which are formed when locked up with water.
The analysis of the results of physical and mechanical investigations of portland cement with applications of meadow waste has shown that their loading allows to significantly increase the strength of this cement stone, due to the formation of an additional amount of sodium sulfate or potassium. Their influence as activators of hardening is most noticeable in the initial terms and gradually decreases with age of hardening. It has been shown that use in the composition of the binder of meadow-based additives and hydrosilics makes it possible to increase the strength of the cement stone by 1.5 times, which is essential for the development of effective composite binders on its basis for work in high temperatures. In this, the presence of fluoride aluminium in hydrosilic in a quantity of 3.3% by weight determines its plastisizing effect on cement.
It has been experimentally stated that during the heating of concrete above 500°C, the destruction of hydrated components of cement stone with the destruction of structural bonds between individual particles with a significant decrease in strength characteristics. In this case, the use of applications provides a partial coupling of CaO in the process of solid phase reactions during heating. It is proved that the use of composite cement, as a binder, due to the presence of its composition of a meadow-based application - accelerates hardening and improves strength characteristics, hydrosilics - increases residual strength at a pressure of up to 1000°С by 2.4 MPa .

The analysis of the problem of extinguishing fires of magnesium and its alloys is carried out. The urgency of studying the problem is confirmed by the fact that during the extinguishing of class D fires there are factors that can complicate the quenching process. Often, these metals actively react with water, which leads to an even greater spread of the fire and even an explosion. Therefore, special fire extinguishers, which have passed the proper test, are more effective in locating the fire and prevent the burning of the powder to form the "tongues" of the flame. In Ukraine, there is no method for testing the effectiveness of fire extinguishants of special purpose for the extinguishing of class D fires. The normative documents have been analyzed, which specify the procedures for testing extinguishing fire-extinguishing special-purpose fire extinguishing class D. Specifically: the methods are described in the international standard ISO 7165: 2017 «Fire fighting – Portable fire extinguishers – Performance and construction» and GOST 53280.5-2009 Fire fighting systems automatic. Extinguishing agents.
Both methods have a number of shortcomings that need to be addressed when creating a Ukrainian fire test method for extinguishing fire extinguishing class D, namely: the dimensions of the metal frame made of sheet steel with a side (500 ± 10) mm, height (150 ± 5) mm for testing with magnesium chips are small; Not specified quantity of gasoline necessary for the rise of magnesium; The gas or oxygen torch used to dissolve magnesium does not provide full-value combustion throughout the area, but only creates separate cells of ignition.
A draft methodology has been developed that determines the fire-extinguishing efficiency of powdered powders used in Ukraine. The required amount of fuel for burning magnesium and its alloys is determined. It was ascertained that for the firing of magnesium chips it is necessary to use at least 127 grams of gasoline of the mark A 92.
Key words: test method, fire extinguishers of special purpose, extinguishing of fires of magnesium alloys
SYNTHESIS OF FRACTIONAL ORDER CONTROLLERS FOR MULTI-LUPP CONTROL STRUCTURE OF FIRE LIFT BASKET TURNING
Authors: Kopchak B. , Kushnir A. , Kravets I. 
Published: October 2019

Introduction. The attempt to get the best dynamic and static characteristics of the basket turn angle complicates the tasks performed by the automatic control system (ACS) basket turn drive. The ACS of the basket turn should meet the following requirements: high speed, smooth acceleration and breaking of the motor, static and dynamic accuracy of the reproduction of tasks trajectories, no overregulation in transition modes, required stability reserve, low sensitivity to coordinate and parametric disturbances, etc. A number of fundamentally different ACSs and methods for their synthesis have been analyzed to provide these requirements. As a result of the analysis, there has been selected a two-loop feedback control system (FCS) of the basket turn with regard to the elastic properties of the arrow, which is synthesized by the method of the generalized characteristic polynomial. Studies have shown that this system allows to provide an aperiodic transition process of the basket turn angle with a given speed and low sensitivity in steady state to the perturbation effect. However, the synthesized FCS transfer functions of the controllers of angular velocity of the motor and the basket have a high order and turned out to be quite complicated in terms of practical implementation.
Purpose. In the article it is proposed to replace these controllers, by approximating them through evolutionary methods, with more compact fractional PІλDμ-controllers or fractional order controllers.
Results. The studies carried out in this work have shown that fractional order controllers are quite advantageous in comparison with the over classical ones, particularly in the case of their application for optimization of electromechanical systems with the following features of their control objects: two masses, including those with the presence of impact; backlash viscosity of the drive friction; nonlinear load and so on.
Replacement of the high-order motor and basket angular speed controllers with more compact PІλDμcontrollers or fractional order controllers has been performed using Optimization Toolbox optimization package in the MATLAB package. This software has been developed for approximation of classical parts with high-order transfer functions by fractional order parts, using a genetic algorithm or a particle swarm optimization for their transition functions.
Conclusion. The conducted research on digital models has confirmed the efficiency of the replacement of high-order motor and basket angular velocity controllers with PІλDμ-controllers or fractional order controllers, whose transfer functions are determined by approximating the transition functions of the controllers by the genetic algorithm method.
