Elastic Hysteretic Properties of Damping Composite Materials for Rail Transport at Low Temperatures under Static and Dynamic Loading

Abstract

Abstract—The stiffness and damping properties of various-thickness samples made of a composite material based on a rubber mixture, rubber fiber composite material, and thermoplastic elastomers of various stiffnesses are studied under static and dynamic loading conditions at a temperature of 23 and –40°C. The composites based on a rubber mixture and the rubber fiber composites are recommended for the dampers that work in regions with low climatic temperatures. The stiffness and damping properties of a real object are assumed to be estimated using the elastic hysteretic properties of a test sample.
