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. Fe-Mn Damping alloy with a combination of high damping capacity and good mechanical properties can provide attractive technical and economical solutions to problems involving seismic, shock and vibration isolation. We have studied the noise and vibration characteristic of Dampalloy and checked Dampalloy reduced noise about 3.9dB and vibration about 15.9 times as compared conventional material through laboratory research. With this result, we obtained a good possibility of material substitution about the bridge expansion joint

The Fe-Mn damping Alloys which combine a high damping capacity with good mechanical properties can provide attractive technical and economic solutions to problems involving fatigue, noise and vibration. This study is aimed at finding its applicability to divided spherical bearing in bridge. The results obtained are summarized as follows : 1) The specific damping capacity of the Fe-Mn damping alloy is superior to that of SM490B. 2) The divided spherical bearing manufactured Fe-Mn damping alloy passes the load test to confirm applicability of that in bridge.
