Abstract
In this paper, a new anti-vibration bearing is proposed to mitigate vertical train-induced vibrations to improve the vibration environment around the elevated urban rail transit. A scale model test is carried out to verify the vibration reduction effect of a new anti-vibration bearing. Test result shows that vibration amplitudes of new anti-vibration bearing at the upper and lower plates are smaller than those of steel bearing while the electromagnetic vibrator is working on the test model. The whole insertion loss of anti-vibration bearing is 13.49 dB, which is 5.32 dB larger than that of steel bearing. For most frequency components, the new anti-vibration bearing can reduce more vibrations than the steel bearing in the vertical direction. Therefore, this kind of bearing is effective to isolate the vertical vibration.
