Damping Composites from Materials with Different Elastic Hysteresis Properties for Sandwich Shock Absorbers of Railroad Transport

  • Published:
Inorganic Materials: Applied Research Aims and scope

Abstract

The damping composites from the materials with different elastic hysteresis properties have been studied at dynamic loads and temperatures of +23°C and –40°C. A sandwich shock absorber for a rail damping element that is 14 mm in thickness from fiber-reinforced rubber composite and thermoplastic elastomer, which combines the advantages of each material, has been developed. A procedure for the choice of elastic hysteresis characteristics of sandwich shock absorbers and a mathematical model of a wagon–track multiple-mass vibration system making it possible to evaluate the applicability and performance of such shock absorbers have been proposed.
