Abstract: The aim of this study was to measure, analyze and identify the complex modulus of elasticity of rubber segments pressed onto the "Hong Kong" rubber-damped railway wheels in relation to the deformation nodes of wheel vibrations. The main goal was to improve the description of the frequency dependence of the material constants of the rubber segments pressed between the disk and the rim with large pre-stress (about 20%) during the production of the rubber-damped wheel. The solution consists of two parts: a) the modal analysis of the railway wheel, b) the identification of the frequency dependence of Youngś modulus and the loss factor of the wheel rubber by the finite element method. The obtained results are in good accordance with the behavior of hard synthetic rubber.
