Показана взаимосвязь вибраций связанных элементов системы, описываемая передаточными функциями. Выявлено возникновение резонансных колебаний в направлениях, ортогональных направлению возмущающего воздействия и предложен метод их расчета и обоснована возможность их определения на базе измерения значений амплитуд колебаний в одном направлении и закономерностей соотношения амплитуд вибраций.</p></abstract><trans-abstract xml:lang="en"><p>The paper describes a method for condition monitoring of a complex mechanical system based on pre-computer FEM simulation of vibrations. The interrelation of vibrations of the connected elements of the system, described by transfer functions, is shown. The occurrence of resonant vibrations in directions orthogonal to the direction of the disturbing effect is revealed. The method for calculating of orthogonal direction vibration amplitudes can be based on measuring the values of the of vibrations in one direction and the regularities of the ratio of the amplitudes of vibrations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерное моделирование</kwd><kwd>метод конечных элементов</kwd><kwd>вибрации</kwd><kwd>вибродиагностика</kwd><kwd>технологическое оборудование</kwd><kwd>механическая система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer modeling</kwd><kwd>finite element method</kwd><kwd>vibrations</kwd><kwd>vibration diagnostics</kwd><kwd>technological equipment</kwd><kwd>mechanical system</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">Барков, А.В.
