| Summary: | Magnetorheological elastomer (MRE) is a type
of smart material made of natural or synthetic rubber filled
with micron-sized magnetic particles. Its shear modulus
and elasticity can be controlled by applying an external
magnetic field. In this study, a mounting system model is
used to obtain displacement transmissibility factor. In the
experimental analysis, three different MRE samples are
manufactured by varying the percentage of magnetic par-
ticles. The experimental investigations are carried out to
characterize the quasi-static properties of these MREs by
attaching them with universal testing machine in com-
pression and tensile mode. In both modes, different cur-
rents and velocities are applied to the samples. From the
experimental results, a proportional relationship has been
observed among the resisting force from MREs and applied
excitation current, displacement and velocity. In most
cases, the force has increased with the increasing per-
centage of magnetic particles in the sample. However, the
highest force is obtained from the sample with 30% mag-
netic particles, at 2 A current and velocity of 4 mm/min.
The results observed in this research would be useful for
vibration control in applications such as engine mounting
system. |
