Abstract
A metro rail corrugation measurement method based the Seq2Seq model and vibration and noise data fusion comprises the following steps: Constructing a time series data set corresponding to floor longitudinal acceleration and train speed based on historical data of metro trains; Constructing the metro train mileage matching prediction model based on the Seq2Seq model, training the metro train mileage matching prediction model by time series data sets, and inputting the inside floor longitudinal acceleration of the metro train to be detected into the trained metro train mileage matching prediction model to obtain the running speed of the metro train to be detected. According to the vibration and noise data of the metro train to be detected, the vibration and noise composite index of the rail corrugation is calculated to determine the wavelength and amplitude information corresponding to the rail corrugation.
