Представлено решение задачи определения основной частоты колебаний трехслойной пластины, жестко закрепленной в центральной точке. Для решения динамической задачи применен обобщенный метод Галеркина. Получена формула для определения основной частоты колебаний трехслойной пластины, закрепленной в центральной точке.
In the article the problem of determination of fundamental frequency of the sandwich plate, tightened in the central point, is solved. Variation equations of plate dynamics were solved by generalized Galerkin method. The formula for fundamental frequency determination is obtained.
