Field measurement and evaluation of vibration in different areas of a metro depot
Field measurement and evaluation of vibration in different areas of a metro depot
This paper presents a study of the characteristics of a railway vibration at three key sections containing different track structures in a metro depot. The results show that the vertical and horizontal vibration acceleration levels are proportional to train speed. The Z-weighted vertical acceleration levels obtained showed that the vibration source strengths at the ballast foot of the testing line and the throat area were very close. The vibration attenuation at the repair line was larger than that of the testing line. In the throat area, the peak frequency of vibration obtained at the ballast foot (2.5 m) could be shifted to a lower frequency band by using polyurethane sleepers instead of standard concrete sleepers. Polyurethane sleepers can help to reduce vertical vibration in a frequency band of 0–10 Hz. The vibration levels would satisfy the limits given in the ISO2631-2-2003 (2013) for any location more than 5 m away from the source at the testing line and 2.5 m away from the source at the repair line and throat area.

Abstract
This paper presents a study of the characteristics of a railway vibration at three key sections containing different track structures in a metro depot. The results show that the vertical and horizontal vibration acceleration levels are proportional to train speed. The Z-weighted vertical acceleration levels obtained showed that the vibration source strengths at the ballast foot of the testing line and the throat area were very close. The vibration attenuation at the repair line was larger than that of the testing line. In the throat area, the peak frequency of vibration obtained at the ballast foot (2.5 m) could be shifted to a lower frequency band by using polyurethane sleepers instead of standard concrete sleepers. Polyurethane sleepers can help to reduce vertical vibration in a frequency band of 0–10 Hz. The vibration levels would satisfy the limits given in the ISO2631-2-2003 (2013) for any location more than 5 m away from the source at the testing line and 2.5 m away from the source at the repair line and throat area.
