EXPERIMENTAL STUDIES OF ACOUSTIC VIBRATION DAMPING COMPOSITE SYSTEMS WITH A VIEW TO THEIR APPLICATION IN THE DAMPING OF VIBRATIONS IN STEEL RAILWAY BRIDGES

EXPERIMENTELLE UNTERSUCHUNGEN AN KOERPERSCHALLDAEMPFENDEN VERBUNDSYSTEMEN IM HINBLICK AUF SCHALLDAEMPFUNGSMASSNAHMEN AN STAEHLERNEN EISENBAHNBRUECKEN

This paper deals with the problem of abatement of noise from steel railway bridges through the application of large-area sandwich-type steel-plastic composite systems, which by damping acoustic flexural vibrations lead to substantially reduced sonic emission into the atmosphere. The mode of operation of sound attenuating composite systems and the acoustic engineering problems involved in steel railway bridges are discussed. In addition, the requirements peculiar to bridge construction are considered, such as the fastening of the composite systems onto the steel structure, the corrosion behavior of the structure in the composite region, and the creep behavior of the composite systems under mechanical vibrating loads in the presence of temperature effects.
