Abstract

The study is performed to investigate the damping characteristics of the developed vibroprotection system with the double flat spring elastic element. Damping of vertical and horizontal natural oscillations of mass is studied under the change in the external electric field applied to the electrically controllable damping material.

It is determined that the logarithmic decrement of vertical natural oscillations increased almost twofold, and the logarithmic decrement of horizontal natural oscillations increased by a factor of 6 with the change of electric field from 0 to 1.2 kV/mm.
