Актуальность исследования обусловлена широтой применения данных структурных элементов конструкций.</p><p>Для определения частот собственных колебаний применялись расчетные методы, в частности аналитический расчет и расчет методом конечных элементов. За основу аналитического расчета было принято уравнение движения тонкой прямоугольной пластины. Затем применялся асимптотический метод, учитывающий динамический краевой эффект. В результате были определены частоты собственных колебаний пластины. Расчет по методу конечных элементов проводился в двух программных комплексах: «Лира» и SolidWorks. Была создана твердотельная модель пластины с датчиками, с помощью которой были рассчитаны частоты собственных колебаний, определены коэффициенты массового участия.</p><p>Для подтверждения правильности результатов аналитических расчетов проводились экспериментальные исследования колебаний прямоугольных пластин на вибростенде. Использовался метод плавного изменения частоты синусоидальных колебаний. По значениям амплитуд виброускорений датчиков были построены спектральные графики колебаний пластины.</p><p>В результате выявлены определенные расхождения в значениях частот собственных колебаний в зависимости от применяемого метода. В исследовании не принимались во внимание частоты с малым коэффициентом массового участия.</p></abstract><trans-abstract xml:lang="en"><p>The paper investigates free vibrations of rectangular metal plates. The finite element method and analytical calculation are particularly used to determine the vibration frequency. The analytical calculation is based on the equation of motion of a thin rectangular plate. The asymptotic method is applied to determine the dynamic edge effect. As a result, the free vibration frequency is determined for the rectangular metal plate. The finite element analysis is performed in Lira and SolidWorks software packages. For this, a solid plate model with sensors is created to measure the free vibration frequency; the effective mass participation factor was determined.</p><p>The plate vibration tests were conducted to confirm the results of analytical calculations. The method of smooth sinusoidal vibrations is used. Spectrum graphs of the plate vibrations are suggested based on the vibration acceleration of sensors. Errors are identified in the free vibration frequencies depending on the applied method. The paper does not consider frequencies with the low effective mass participation factor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>колебания</kwd><kwd>пластина</kwd><kwd>частота</kwd><kwd>вибростенд</kwd><kwd>метод конечных элементов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vibrations</kwd><kwd>plate</kwd><kwd>frequency</kwd><kwd>effective mass participation factor</kwd><kwd>vibration table</kwd><kwd>finite element method</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">Liew K.M., Hung K.C., Lim M.K.
