Abstract
1. Способ динамического гашения колебаний, заключающийся в том, что гасят колебания со стороны основания с помощью инерционных масс, расположенных на стыках рычагов, отличающийся тем, что обеспечивают динамическое гашение колебаний в широком диапазоне частот за счет инерционных сил дополнительных масс, установленных в местах соединений нижних рычагов с регулируемым пневмоэлементом.2. Устройство для динамического гашения колебаний, содержащее пружину, расположенную перпендикулярно основанию, одним концом прикрепленную к вибрирующей поверхности, а другим к объекту защиты, и ромбовидную систему рычагов, причем в месте соединения нижних и верхних рычагов установлены шарниры, отличающееся тем, что дополнительно установлены два упругих элемента, расположенных параллельно основанию, один представляет собой пружину с дополнительными массами на концах, соединяющую нижние рычаги ромбовидной системы, другой выполнен в виде пневмоэлемента, предназначенного для регулирования общей жесткости системы, концы которого соединены с продолжениями нижних рычагов и в местах соединения находятся дополнительные массы, обеспечивающие создание инерционных сил, действующих во встречном направлении относительно возмущающих сил основания на всех частотах заданного диапазона.1. The method of dynamic damping, which consists in damping vibrations from the base using inertial masses located at the joints of the levers, characterized in that they provide dynamic damping of vibrations in a wide frequency range due to the inertial forces of the additional masses installed at the joints lower levers with adjustable pneumatic element. 2. A device for dynamic damping of oscillations, comprising a spring located perpendicular to the base, attached at one end to a vibrating surface, and the other to the object of protection, and a diamond-shaped lever system, wherein hinges are installed at the junction of the lower and upper levers, characterized in that two elastic element located parallel to the base, one is a spring with additional masses at the ends, connecting the lower levers of the diamond-shaped system, the other is made in the form Pneumoelements intended for controlling the overall stiffness of the system, the ends of which are connected with extensions of the lower arms and the joints are additional weight to ensure the creation of inertia forces acting in the opposite direction relative to the base of perturbing forces at all frequencies a predetermined range.
