Sleeper with damping element based on dissipative bulk or granular technology

摘要

The invention relates to a railway sleeper (46) including at least one damping element (10) for absorbing mechanical excitations (43), wherein the at least one damping element (10) is embedded into a recess (80) of the sleeper (46), characterized in that the at least one damping element (10) comprises a container (14) encapsulating a viscoelastic material (12), wherein the container (14) is pressurized to a pressure level (p), at which the damping element's (10) frequency and/or rate for absorbing a maximum energy substantially matches a frequency and/or rate of the mechanical excitation (43).
