Abstract
A micro–nano magnetorheological elastomer (MRE) containing Fe

nanoparticles was prepared, and its mechanical properties were analyzed. A microscopic static force model was used for MREs with different concentrations of nanomagnetic particles. To investigate the mechanical properties, an experimental platform was built, and its magnetic field flux was simulated with finite-element software. The results show that the maximum compressive elastic modulus for MREs containing 10% Fe

nanoparticles is 2.89 MPa, which is 149% that of a traditional MRE under the same magnetic field. The normal stress of micro–nano MRE was significantly improved, which could be useful in the development of high-performance MREs.
