Analyzed various tests to check the wire that moves through the die to increase its plasticity and improve the quality of the hairs. Based on the calculated and experimental data, a comparison was made of energy consumption when creating a given temperature distribution by direct transmission of electric current through a moving wire and its heating in a continuous muffle furnace. Mathematical modeling of the heating parameters of each method is performed on the corresponding mathematical model. The applied mathematical model is based on the boundary value problem for the heat equation. To confirm the adequacy of the mathematical model, experimental studies were carried out with temperature measurements at the control points of the heating zone. Calculations were made of the parameters of wire heating by pulsed current, which forms the electroplastic effect during drawing. According to the results of the study, it was found that in order to increase the plasticity of the wire during the drawing operation, it is advisable to use a pulsed current.

Knowledge about eye movement is of great theoretical and applied importance. Analysis of the relationship of the oculo-motor system (OMS) with the central nervous system, with the content of mental processes, with various forms of activity (behavior, activity, communication) helps to study the mechanisms of the brain and their disorders, to identify the dynamics of psychophysiological states, patterns of perception, thinking, intentions and attitudes of the individual. A significant drawback of the existing equipment that implements this technology is the fundamental impossibility of measuring the dynamic and nonlinear characteristics of OMS - a promising direction in the development of modeling biological objects - without knowledge of which it is impossible to build an effective control system. To eliminate this shortcoming, the traditional structure of the system for tracking the behavior of the pupil from video recording was further developed in this work, which made it possible to determine the dynamic characteristics of the human visual system from experimental observations of “input-output” (the identification problem).

This paper provides the model of the composite material using the energy method to determine its effective energy dissipation characteristics. There are employs finite element modelling of a representative volume element and setting equal its strain energy complex values to the equivalent homogeneous material volume one. The results of the calculations imply that a composites representative volume element can be used to analyze the energy dissipation characteristics in the viscoelastic composite components structures elements, which are made of them. Thus, the analysis of the ratio between the dissipated energy in the epoxy matrix material and dissipated energy in the layers of carbon/epoxy laminates for the different values of carbon volume fraction is performed using the model. The efficiency of the proposed model aimed at the dissipative properties of various types of composites is also shown.

The problem of optimal design of a symmetrical double-lap adhesive joint is considered. It is assumed that the main plate has a constant thickness, while the thickness of the patchs can vary along the length of the joint. The optimization problem is to find the optimal length of the joint and the optimal profile of the patches, which provide a minimum mass of the structure in the presence of strength constraints. The classical Goland-Reissner model was used to describe the stress state of the joint. The corresponding system of differential equations with variable coefficients is solved using the finite difference method. For the numerical solution of the optimization problem, a genetic optimization algorithm was used. One model problem are solved.

The technique of digital algorithmic correction of dynamic properties of the electric drive is offered. The application of the technique allowed achieving quasi-invariant properties of the electric drive in relation to the angular velocity of its rotor. The method allows synthesizing three digital algorithms: proportional-differential regulator; regulator with correction drive modal dynamic properties; algorithmic meter of angular speed of electric drive rotor. The joint use of these three algorithms allows to reduce the mean-square error of tracking the optimal law of motion by nearly 4 times and to reduce the influence of shock (impulse) disturbances by 3 times. Thus, it becomes reasonable and possible for practical implementation to use only an algorithmic method of improving the dynamic properties of electric drive, which does not require the use of additional equipment.

The results of a study of the operating conditions of the main power equipment of a three-phase combined compensation rectifier are presented. Due to the novelty of the circuit and the complexity of electromagnetic processes, the study was carried out without taking into account the inductance of the AC circuit. The dynamics of changes in the value of currents and voltages of the equipment depending on the value of the turn-on delay of the commutating link transistors is analyzed. Conclusions are drawn about the advantages of the proposed circuit implementation of the converter, implemented according to the three-phase combined compensation circuit, in comparison with the compensation converters of the previous generation.

Deformation of functionally graded carbon nanotubes reinforced composite joined spherical-cylindrical-spherical shell under the actions of impact loads is considered. The dynamic of this structure is analyzed numerically. Higher-order shear deformation theory is applied to describe the structure stress-strain state. The continuity conditions of the spherical-cylinder junction are implemented. The displacements projections are chosen in the special form to satisfy these continuity conditions. A nanocomposite material is selected in order to ensure its maximum strength at minimum weight of the joined shell.

A two-loop high-speed structure is proposed to regulate the electric mode (EM) of an arc steel melting furnace (AF) is proposed. A solution to improving the indices of the dynamics of EM coordinate regulation indices has been developed and studied. A comparative analysis of the dynamic indices of the proposed two-loop structure of fuzzy regulation of the coordinates of the EM arc furnace DSP-200 and the ARDM-T-12 serial arc power controller was performed. The time dependences of the main EM coordinates and the integral values of the quality indices of dynamics and energy efficiency during the regulation of random EM disturbances have been obtained on the computer model. The comparative analysis of the obtained dynamic indices has confirmed the effectiveness of the proposed high-speed two-circuit structure of the EM coordinate control system compared to the ARDM-T-12 controller.
