Analysis on the Measurement of Vehicle-Induced Vibrations in the Throat Area of the Subway Depot
摘要
Abstract
The monitoring on the vehicle-induced vibrations monitoring was carried out in the throat area and the cover of the throat area of a newly built subway depot in China.The monitoring results show that the cover vibration in the throat area is mainly concentrated in the low frequency range(10～50 Hz),and the peak frequency mainly occurs in 14.7～30.6 Hz.The vibration characteristic frequency band of the track area in the throat area ranges from 10～300 Hz,and the peak frequency is mainly concentrated in 50～150 Hz.The vibration acceleration is obviously attenuated with the increasing of the distance from the source of vibration.The vibration acceleration generated in the turnout area is greater than that in the straight line area,and the greater the speed of the train,the greater the peak vibration acceleration generated.The vibration acceleration of the railroad track area and the roof cover increases and then decreases with the increase of frequency,the peak frequency of the vibration acceleration of the roof cover is in the range of 10～20 Hz,and the peak frequency of the vibration acceleration of the railroad track area is in the range of 25～80 Hz.关键词
