Abstract

Magneto-rheological elastomers(MRE) are similar to magnetorheological fluids. Thus, rheological properties of MRE can be also controlled by an applied magnetic field. The MRE in this experiment is a mixture of natural rubber(NR), carbonyl iron powder(CIP), ZnO, and sulfur. Three specimens were prepared and tested by using the vibration testing instruments. The magnetic field was generated by the electromagnets. Natural frequencies of the oscillator were changed by the applied magnetic field. The properties of the MRE were increased due to magnetic field strength.
