This article contains the results of research on the vibration characteristics of elastomer samples. Experimental studies of the dynamic properties of magnetoactive elastomer materials under the action of magnetic fields on a vibration complex are conducted. A kinematic sinusoidal excitation is given on the table of the vibrator from the side of the support on the tested product. The accelerations at the sample output are recorded. Oscillograms of accelerations at the input and output of the sample under the action of a magnetic field are obtained. The range of displacement of resonant frequencies under the influence of a magnetic field is shown. The justification for creating an electromagnet lifting force that overcomes the elastic force of the test material is given. Computational modeling is performed to create an elastic deformation of a magnetoactive elastomer, both static and dynamic, using a magnetic field.
