MAGNETICALLY CONTROLLED HYDRAULIC VIBRO BEARING Russian patent published in 2019 - IPC F16F13/08 

FIELD: machine building.

SUBSTANCE: invention relates to the machine building. Vibration mount comprises housing with diamagnetic metal partition wall, in which throttling channels are made connecting chambers filled with damping magnetorheological fluid. Working chamber is limited by support plate and elastic shell, and compensating chamber by membrane. Partition is made in the form of two coaxial cylinders arranged inside the core with inductor windings offset relative to each other by 360/n degrees, where n=3, 6, 12. Throttling channels are longitudinal channels made in central part of inner cylinder, and cylindrical gap between inner and outer cylinders. In upper and lower bases of outer cylinder there are holes connecting cylindrical gap with chambers. Inductor windings are connected to alternating voltage converter, the input of which receives signal from the first accelerometer attached to the support board. Second accelerometer located at the output of the magnetically controlled hydraulic vibration support is connected to the output signal recorder.

EFFECT: higher efficiency and reliability of vibratory support due to control of viscosity of damping magnetorheological liquid during its movement in entire working zone.
