Abstract

Magnetorheological elastomers (MREs) are typically comprised of magnetic particles and non-magnetic matrix. Their mechanical properties are dependent on many factors, among which temperature is very important yet lack of understanding due to limited studies. In this paper, experimental study has been carried out to characterise the dynamic properties of MREs under different temperature and magnetic fields. By using the obtained experimental data, the viscoelastic model for rheological properties of MREs is presented based on the generalized Maxwell model and fractional Maxwell model. The experimental results show that temperature has an important influence on the dynamic modulus of MREs made from silicone rubber embedded with iron particles subjected to uniaxial compression. It is found that there is a transition behavior of MREs at about 50℃ for dynamic modulus, i.e. below which the storage modulus of MRE is first decreases with the increasing of temperature up to 50℃ and then increases with the temperature increased.
