DEVICE FOR DAMPING LOW-FREQUENCY VIBRATIONS Russian patent published in 2018 - IPC F16F6/00 F16F9/53 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Device comprises a body made of a non-magnetic material, inside which a cylindrical chamber is formed. Chamber contains a magnetic fluid in a colloidal state. Body of a non-magnetic material is fixed rigidly to an external structure subjected to low-frequency vibrations. Magnet is placed in the chamber in the form of a straight circular cylinder with the possibility of enveloping the magnetic fluid contained in the chamber. In the lateral wall of the cylindrical chamber, a notch is drawn along its entire length, and in the lower and upper walls of the cylindrical chamber, convex elements are made in their central part. To obtain the maximum logarithmic decrement of vibrations at a vibration frequency, a certain relationship is made that relates the frequency to the dimensions and properties of the materials of the components of the device for damping low-frequency vibrations.

EFFECT: wider range of equipment is achieved.
