Noise and vibration is the most problematic thing in the rail way bridges. In this study, we compared the vibration reduction test of two types of Spherical bearing. The results of the experiment were able to get the following conclusion. The elastomer layered spherical bearings vibration reduction performance is two times better than that of the steel type spherical bearing.
