The peculiarity of the suggested approach consists in the introduction of an additional term into the basic equation of oscillations. This term characterizes the presence of a temperature gradient in the systems. The developed theory is applicable to longitudinal oscillations of a rod, but can be extended just as well to the problem of the vibrations of strings, membranes, shaft torsional oscillations, electromagnetic waves, etc. Numerical experiments showed a significant effect of the temperature field in the rod on the nature of the vibrations and displacements of the rod cross-sections in comparison with classical solutions.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрен новый класс модельных представлений в теории колебаний систем, описываемых классическими краевыми задачами для уравнений гиперболического типа. Особенность предложенного подхода заключается во введении в основное уравнение колебаний дополнительного слагаемого, характеризующего наличие в системе градиента температуры. Развитая теория касается продольных колебаний стержня, но с одинаковым успехом может быть распространена на задачи о колебаниях струны, мембраны, крутильных колебаний вала, электромагнитных колебаний и т.д. Проведены численные эксперименты, показавшие существенное влияние температурного поля в стержне на характер колебаний и смещений сечений стержня по сравнению с классическими решениями.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>стержень</kwd><kwd>продольные колебания</kwd><kwd>градиент температуры</kwd><kwd>смещения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rod</kwd><kwd>longitudinal vibrations</kwd><kwd>temperature gradient</kwd><kwd>offset</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">Тихонов А.Н., Самарский А.А.
