Comparison of the Composite Materials Intended for Damping Elements for the Infrastructure of Rail Transport and Rolling Stock

详细

The elastic hysteretic properties of various polymer damping composite materials, namely, a composite material based on a rubber mixture, a rubber fiber composite material, and thermoplastic elastomers, are studied during static and dynamic loading at a load of 20–90 kN and a temperature of 23 and –40°C. The conditions of effective application of each composite material for a damping element for the upper structure of a railway track and rolling stock are determined.
