Abstract
Today there is a large number of vibration-proof materials for the manufacture of shock absorbers in the market of structural materials. For a reasonable choice, it is necessary to perform comparative tests of different elastomers according to several criteria. The paper presents the results of two-parameters comparative tests of three brands of polyurethane elastomers. As the evaluation criteria, the internal friction module and the loss tangent of elastomeric materials under alternating bending with rotation are chosen. High stability of physicomechanical properties of polyurethane elastomers is studied in the entire frequency range of mechanical vibrations.
