Application of High Damping Alloys for Vibration Reduction in Rail Joint Bar

Conventional methods for reducing vibration in engineering designs may be undesirable in conditions where size or weight must be minimized, or where complex vibration spectra exist. Some alloys with a combination of high damping capacity and good mechanical properties can provide attractive techanical and economical solutions to problems involving seismic, shock and vibration isolation. In this paper, it showed the noise and vibration characteristic was compared conventional rail joint to improved rail joint(damping alloy) for reducing noise and vibration. Its applicability to rail joint is discussed.
