【 摘 要 】

The publication examines the emergence of high-frequency vibrations in the elements of the rolling stock and the railway track during the passage of vehicles on bridges. It is proposed to use a viscoelastic damper for oscillation of the superstructure at the place of intersection of the superstructure and transom I-beam supports. As a viscoelastic element, it is proposed to use an element of Kelvin-Voigt type. Installation of damper in the form of Jack or a damping device on a support, which is based on the span of the railway bridge, allows for the regulation of the speed of the underframe on the roadway, depending on the viscosity and elasticity of the damping device or jack, and the regulation of dynamic loads.
