| Abstract |
The endurance of expansion joint manufactured the Fe-Mn damping alloy reducing noise and vibration is analyzed into FEM (Finite Element Method) and fatigue test. The fatigue test have been performed using the expansion joint manufactured Fe-Mn damping alloy and the hydraulic actuator (25tonf). And the results of fatigue test show that the maximum strength is 237.6 ㎫. Also that is 56.6 percent of Fe-Mn damping alloy yield strength (420 ㎫). The loading plate size is prepared 57.7 ㎝×23.1 ㎝ and the loading plate"s set position is located on expansion joint. The expansion joint manufactured the Fe-Mn damping alloy had not presented breaking behavior against 2,000,000 times fatigue test and identified the fatigue endurance. |
