Magnetorheological elastomers is an intelligent material which can sense and judge the external magnetic field and change its mechanical properties. In this paper, functional carbon nanotubes are added to polyurethane magnetorheological elastomers. According to the micro-mechanical finite element calculation, the mechanical parameters of the equivalent matrix composed of carbon nanotubes and polyurethane elastomers are obtained. Multi-scale simulation analysis of the magneto-mechanical properties of isotropic magnetorheological elastomers with different volume fractions of carbon nanotubes in tensile, compressive and shear modes using magnetic coupling software. The simulation results show that the magnetorheological elastomer with larger volume fraction of carbon nanotubes has higher storage modulus in the three modes than the magnetorheological elastomer with smaller volume fraction of carbon nanotubes.
