In this paper, a parametric constitutive model based on Abel dashpot is jeff rosenstock buffalo established in a simple form and with clear physical meaning to deduce the expression of dynamic mechanical modulus of MREs.Meanwhile, in consideration for the pressure stress on MREs in the experiment of shear mechanical properties or the application to vibration damper, some improvements are made on the particle chain model based on the coupled field.In addition, in order to verify the accuracy of the overall model, five groups of MREs samples based on silicone rubber with different volume fractions are prepared and the MCR51 rheometer is used to conduct the experiment of dynamic mechanical properties based on frequency and magnetic field scanning.Finally, experimental results indicate that the established model fits well with laboratory data; namely, the relationship between the read more dynamic modulus of MREs and changes in frequency and magnetic field is well described by the model.
