Abstract

Изобретение относитс  к машиностроению, а именно к средствам гашени  вибраций различных объектов. Целью изобретени   вл етс  повышение эффективности гашени  вибраций, достигаемое расширением диапазона рабочих частот. Вибрации объекта 8 гас тс  за счет колебаний грузов 1 и камер 4 на струне 3 в режиме антирезонанса. Расширение полосы рабочих частот обеспечиваетс  множественностью частот собственных колебаний виброчастот и интенсивным рассеиванием энергии вибрации при ударном взаимодействии грузов 1 и камер 4 со струной 3, при котором происходит деформаци  последней. 2 ил.The invention relates to mechanical engineering, namely to means of damping vibrations of various objects. The aim of the invention is to increase the vibration damping efficiency achieved by expanding the range of operating frequencies. The vibrations of the object 8 are extinguished by the oscillations of loads 1 and chambers 4 on string 3 in the antiresonance mode. The expansion of the operating frequency band is provided by the multiplicity of natural vibration frequencies of the vibration frequencies and the intense dissipation of the vibration energy during shock interaction of the loads 1 and chambers 4 with the string 3, at which the latter deforms. 2 Il.
