Reducing the influence of the disadvantages characteristic of a branched multi-connected system is possible by creating control systems based on mathematical models of the considered electromechanical systems (EMS). The full mathematical model takes into account the number of EMS motors, gear backlashes, elasticity of shafting, the effect of dissipative forces, etc. Disadvantage of this approach is complexity of such models, which leads to high computational costs and time expenditure for their implementation. To analyze dynamic processes arising under acceleration and deceleration conditions of the electromechanical system of the converter tilting mechanism, it is proposed to use a simplified equivalent simulation model, which would take into account changing the EMS natural oscillation frequency for any operation conditions based on process and design features. Based on the simulation model analysis, it was concluded that it is necessary to assess mechanical loads in the system by comparing their current and basis values, as well as taking into account the damping properties of the electric drive. To reduce dynamic loads, it is proposed to form a law of changing the control voltage using an intensity generator, which reduces the risks of occurrence of elastic moments, significantly exceeding those permissible for this class of mechanisms. The results of thermal and vibration diagnostics for assessing malfunctions of key units of the converter tilting mechanism, as well as assessing the system behavior based on the Matlab Simulink model with varying shafting elasticity and normalized gear backlashes, showed significant effect of the latters on the dynamic loads.</p></abstract><trans-abstract xml:lang="ru"><p>Многодвигательным электроприводом оснащены многие тяжелые машины и механизмы горно-металлургической отрасли, например кислородные конвертеры. Уменьшение влияния недостатков, характерных для разветвленной многосвязной системы, возможно за счет создания систем регулирования на основе математических моделей рассматриваемых электромеханических систем (ЭМС). В полной математической модели учитывается число электродвигателей ЭМС, зазоры в передачах, упругости валопроводов, влияние диссипативных сил и т.д. Недостатком такого подхода является сложность таких моделей, что приводит к большим вычислительным и временным затратам при их реализации. Для анализа динамических процессов, возникающих в режимах разгона и торможения электромеханической системы механизма наклона конвертера, предлагается использовать упрощенную эквивалентную расчетную модель, которая учитывала бы изменение собственной частоты колебаний ЭМС для любого режима работы на основе технологических и конструктивных особенностей. На основании анализа расчетной модели сделан вывод о необходимости оценки механических нагрузок в системе методом сравнения их текущих и базовых значений, а также учет демпфирующих свойств электропривода. Для снижения динамических нагрузок предлагается сформировать закон изменения управляющего напряжения с помощью задатчика интенсивности, снижающего риски возникновения упругих моментов, значительно превосходящих допустимые для данного класса механизмов. Результаты термо- и вибродиагностики для оценки неисправностей основных звеньев механизма наклона конвертера, а также оценка поведения системы на базе модели Matlab Simulink при варьировании упругости валопроводов и приведенных зазоров показали существенное влияние последних на динамические нагрузки.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>конвертер</kwd><kwd>электромеханическая система</kwd><kwd>валопровод</kwd><kwd>динамика</kwd><kwd>расчетная схема</kwd><kwd>термо- и вибродиагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>converter</kwd><kwd>electromechanical system</kwd><kwd>shafting</kwd><kwd>dynamics</kwd><kwd>design model</kwd><kwd>thermal and vibration diagnostics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кожевников С.
