Математическое описание составлено в форме уравнения Лагранжа 2-го рода. Система уравнений решена относительно упругой деформации спинки сидения оператора методом Рунге-Кутта, с помощью среды программирования MathCAD. Апробация модели осуществлена на примере серийно выпускаемых валочно-пакетирующих машин ЛП-19А.</p></abstract><trans-abstract xml:lang="en"><p>A dynamic model of the system «operator-feller-bunchermachine-object of labortree » has been developed. The mathematical description is in the form of the Lagrange equation of the second kind. The system of equations is solved for the elastic deformation of the operator's seat back by the Runge–Kutta method, using the MathCAD programming environment. Approbation of the model was carried out on the example of commercially available feller-bunchers machines LP-19A.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>валочно-пакетирующая машина</kwd><kwd>математическая модель</kwd><kwd>колебания</kwd><kwd>вибрация</kwd><kwd>оператор</kwd></kwd-group><kwd-group xml:lang="en"><kwd>feller-buncher machine</kwd><kwd>mathematical model</kwd><kwd>fluctuations</kwd><kwd>vibration</kwd><kwd>operator</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">Александров В.А., Александров А.В.
