| Résumé: | This work deals with the active control of the vibrations of mechanical structures
incorporating magnetorheological elastomer. The damping coefficient and shear modulus of the
elastomer increase when exposed to a magnetic field. Compared with the vibration control where
the elastomer is permanently exposed to a magnetic field, the control of this process through
time reduces vibrations more effectively. The experimental study for the vibrations of a sandwich
beam filled with an elastomer is conducted, followed by a numerical study using the Abaqus code.
The vibration damping is found to be dependent on the loading rate of micro-size ferromagnetic
particles in the elastomer |
