Zadorozhnia I. Improvement of dynamic loading of main electrical drive of the hot rolling mills

Transitional processes in the electromechanical system of main electrical drive of cages of the hot rolling; development of method of synthesis of parameters of main electrical drive of cages of figure of the hot rolling for the decline of the dynamic loading due to active damping of resilient vibrations; theory of automatic control, theory of electrical drive, theory of optimum management, and physical simulation techniques; in the electromechanical system got analytical dependence, that allows to estimate a degree of influencing parameters of electromagnetic and mechanical subsystems and on the damping action of electrical drive. Correlation of intercommunication of parameters of the electromechanical system, which secure a maximum degree of damping of resilient mechanical vibrations both in electromagnetic and in mechanical subsystems are got. A method of synthesis of parameters of the electromechanical system of drive of the hot rolling mills on the basis of criterion of minimum of swaying with compensation of forces of resilient communication by forces of inertia communication is developed. Methods of synthesis of the systems of the inferior adjusting and modal management with the optimum tuning of regulators are offered; for the first time development of method of synthesis of parameters of the electromechanical system of main drive of the hot rolling mills, that allows for the given class of drives to realize a maximum degree of damping in the electromechanical system taking into account dissipation in the mechanical subsystem; subsequent development of method of synthesis of the systems of inferior adjusting and modal management with the optimum tuning of regulators with minimum of dynamic loading; JSC "Novokramatorsky Machine-building plant" (Kramatorsk), in the educational process of department of the electromechanical automatic systems of Donbass State machine-building academy (Kramatorsk); electromechanical, electrical engineering.
