Research on Metro Vehicle Vibration with Regard to Route Conditions
With the development of underground rail, the problem that vehicle vibration affects the vehicle’s life-span and harms the health of the passenger has been concerned. In this paper, a vibration test system has been formed with data collecting instrument and acceleration sensors to collect the signals of the metro vehicle floor when it running at the ATO (Auto Train Operation) mode in the tunnel, Analyzing the regulation of vehicle vibration signal change that come with the change of the route condition, such as curve, slope, and so on. Obtain the relationship between the road condition and vehicle vibration. The analysis result shows that, the vehicle vibration not only be affected by the structure of the vehicle itself and the geological condition on which the track laid, but also has close relationship with the route condition.
