Abstract [en]

The preload dependence of magnetosensitive rubber is experimentally studied along with the influence of frequency, vibrational amplitude and magnetic field strength. The material studied is an iron particle filled natural rubber with a volume particle fraction of 33%, which is close to the optimal particle concentration. The results of the measurements show that an increased preload decreases the influence of magnetic field strength and they also suggest that an increase in the magnetic field reduces the influence of the preload. Measurements of the magnitude of the dynamic shear modulus also display a preload dependence. These results imply that in a description of these materials, the preload should be taken into account, especially since magnetosensitive elastomers are used in applications where they are often exposed to preloads.
