Разработана математическая модель динамической системы: Валочно-пакетирующая машина - предмет труда - дерево . Математическое описание составлено в форме уравнения Лагранжа 2-го рода. Система уравнений решена методом Рунге-Кутта, с помощью среды программирования MathCAD. Апробация модели осуществлена на примере серийно выпускаемых валочно-пакетирующих машин ЛП-19А в режимах разгона и стопорения. In article the dynamic model of system is developed the operator - skidding tractor - tree bunch . The mathematical description is worked out in the form of the equation of Lagrange second number. The system of the equations is solved concerning elastic deformation of the suspension seats. Model approbation is carried out on an example of serially felling and skidding machine LP-19A.
