Целью исследования является изучение работы многопролётных балок с точечными массами при одновременном действии векторных кинематических и силовых нагрузок с учётом влияния упругодемпфирующих опор.Метод. Исследование основано на решении краевой задачи и моделировании.Результат. Исследованы свободные поперечные колебания многопролётных балок постоянного сечения (в пределах каждого j –го пролёта Aj, и Gj) с учётом упругодемпфирующих дискретных опор. Рассмотрены свбодные и вынужденные гармонические колебания балки от векторных кинематических и силовых возмущений. Приведены примеры решения для различных условий закреплений трёхпролётной балки при разных точечных массах.Вывод. Авторскую разработку можно адаптировать к колебаниям континуально-дискретных стержней. Представленный алгоритм позволяет определять собственные частоты и формы свободных колебаний, а также рассчитывать многопролётные стержни на одновременное действие векторных кинематических и динамических нагрузок.</p></abstract><trans-abstract xml:lang="en"><p>Objective. The aim of the study is to study the operation of multi-span beams with point masses under the simultaneous action of vector kinematic and force loads. Taking into account the influence of elastic-damping supports.Method. The study is based on the solution of the boundary value problem and modeling.Result. Free transverse vibrations of multi–span beams of constant cross-section (within each j-th span Aj, and Gj) are investigated taking into account elastic-damping discrete supports. Free and forced harmonic vibrations of the beam from vector kinematic and force perturbations are considered. Examples of solutions for various conditions of fixing a three-span beam at different point masses are given.Conclusion. The author’s development can be adapted to the fluctuations of the continuo-discrete rods. This algorithm allows you to determine the natural frequencies and forms of free oscillations. It is also possible to calculate multi-span rods for the simultaneous action of vector kinematic and dynamic loads.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>балка</kwd><kwd>вязкое трение</kwd><kwd>упругая опора</kwd><kwd>частота</kwd><kwd>амплитуда</kwd><kwd>комплексные функции</kwd><kwd>собственные формы</kwd><kwd>динамические и кинематические векторные возмущения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>beam</kwd><kwd>viscous friction</kwd><kwd>elastic support</kwd><kwd>frequency</kwd><kwd>amplitude</kwd><kwd>complex functions</kwd><kwd>eigenforms</kwd><kwd>dynamic and kinematic vector perturbations</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">Бидерман В.Л.
