FIELD: machine building.
SUBSTANCE: invention relates to machine building. Formulate modes of dynamic vibration damping in mechanical systems with several degrees of freedom. Two mass-inertia elements are connected with each other by a chain-type spring, resting on a vibrating surface. Additional connections are introduced into the system in the form of a lever mechanism, the reference point of which is fixed to the object of protection with one end of the lever. One end of the lever is fixed to the support surface. Other end is connected to a dynamic absorber through the additional elastic element. It is possible to change the gear ratio of the linkage mechanism with the help of controlled devices.
EFFECT: simplified design, dynamic damping effect of the oscillations simultaneously in two coordinates is achieved.
