Аннотация: Viscoelastic properties of the magnetizable elastomers (ME), which are composite materials consisting of elastomer and ferromagnetic particles, and the influence of a magnetic field on these properties practically had not been studied. In this work the method for experimental determining the viscoelastic properties of ME in a uniform magnetic field is proposed. A mathematical model, which is a generalization of the Kelvin-Voigt model, is built. This model takes into account some internal dry friction in ME caused by the magnetic interaction of the ferromagnetic particles in the field. From the comparison of theory and experiment, the coefficients of elasticity and viscosity are found in this model. It is shown these coefficients depend on the magnetic field.
