Abstract
1. Способ регулирования жесткости виброзащитной системы, заключающийся в установке пружины с положительной жесткостью, отличающийся тем, что включают дополнительные упругие элементы в виде масс и, вращая их вокруг вертикальной оси, создают центробежные силы, обеспечивающие изменение суммарной жесткости устройства, причем вращение масс создает отрицательную жесткость, и она зависит от угловой скорости вращения, определяемой по формуле: ! , ! где m1 - вращающееся массы, создающие центробежную силу; ! ω0 - угловая скорость вращения двухзвенника; ! α0 - угол между плечами двухзвенника. ! 2. Виброзащитное устройство для реализации способа по п.1, содержащее упругие дополнительные элементы, отличающееся тем, что упругие дополнительные устройства представлены в виде отдельных масс, соединенных шарнирно с помощью рычагов с основанием и объектом защиты в возможность создания центробежных инерционных сил вращения вокруг вертикальной оси. 1. The method of regulating the rigidity of the vibration protection system, which consists in installing a spring with positive rigidity, characterized in that they include additional elastic elements in the form of masses and, rotating them around the vertical axis, create centrifugal forces that change the total rigidity of the device, and the rotation of the masses creates a negative stiffness, and it depends on the angular velocity of rotation, determined by the formula:! ! where m1 is the rotating mass, creating a centrifugal force; ! ω0 is the angular velocity of rotation of the two linker; ! α0 is the angle between the shoulders of the two linker. ! 2. Vibration-protective device for implementing the method according to claim 1, containing elastic additional elements, characterized in that the elastic additional devices are presented in the form of separate masses, pivotally connected by means of levers with a base and an object of protection to create centrifugal inertial forces of rotation around the vertical axis .
