The paper presents the problem of damping technological equipment oscillations by electrical systems. A method of reducing the emerging vibrations using dampers with a magnetic fluid is proposed. The variants of the optimal location of the permanent magnets and the interaction of their fields for the effective design of the magneto-liquid damper are considered. The optimal scheme is obtained – “for repulsion”. The analysis of the known statistical data is carried out, and the correlation dependence of the dynamic viscosity on the magnetic field parameters depending on the gap between the permanent magnets is obtained. The values of vibration energy dissipation for the proposed magnetic- liquid damping method are obtained. The universality and adaptability of this method of damping vibrations in the process of reducing the vibrations of the technological equipment have been proved.
