摘要： 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.

摘要： A device (9, 9a) for estimating a current wheel diameter of a wheel of a rail-based vehicle on a predetermined network of routes includes an interface (8) for collecting vibration data (5) of at least one wheel acting on the rail-based vehicle as an acceleration of the rail-based vehicle. The vibrations detectable using at least one wireless sensor (2a, 2b, 2c, 2d) arranged proximate the at least one wheel. A computing unit is configured for generating a predicted speed on the basis of the vibration data (5). A comparator unit is configured for estimating a wheel diameter based on differences between the predicted speed and an identified, corresponding ground truth speed (17).

摘要： A disposable lubrication tank liner for a rail lubricating system, including an upper sidewall portion, a lower outlet portion, and an intermediate edge surface. The upper sidewall portion has a plurality of generally vertically disposed walls extending downwardly from an upper flange surface. The vertically disposed walls partially define a reservoir space for holding rail lubricant. The lower outlet portion includes a plurality of angled wall portions converging inwardly to a lower flange surface to further define the reservoir space. Further, the intermediate edge surface connects the upper sidewall portion and the lower outlet portion.

摘要： A system and method for automating railroad maintenance for a tie gang using electronic tie marking (ETM) configured to optimize railroad asset maintenance. The system enables the automating of an adaptive maintenance process for the asset that is being maintainanced. The system can identify a railroad asset scheduled for maintenance using various forms of inspection including real-time kinematic (RTK)-corrected GPS data, radar signal processing data, and real-time imaging. The system also provides for the acquisition and upload of asset pictures for verification and analysis of a railroad asset. The system can identify a next location to perform maintenance and can calculate an optimum path based on sensor input incorporating machine-specific and environmental characteristics. The system further can provide a customizable user interface to identify, track, and process information related to maintenance of the railroad asset.

摘要： An online high-precision measuring device for full-size parameters of a wheel set of a rail transit vehicle, includes: a first laser sensor, a second laser sensor, a third laser sensor, and a polygon measuring module that are configured to measure multiple parts of the wheel set. The first laser sensor is arranged on an inner side of a track at a certain angle. The second laser sensor is arranged below the track at a certain angle. The third laser sensor is arranged on an outer side of the track at a certain angle. The polygon measuring module is butted with the track. The device can realize online pass-through non-stop measurement of the full-size parameters of the wheel set of the rail transit train accurately, such as tread wear, equivalent conicity and wheel polygon.

摘要： A railroad wheel impact load detection test panel includes a secondary instrumentation rail proximate a field side of a primary or running rail of a section of railroad track, and elevated a prescribed distance so that the wheels of a rail car traverse the instrumentation rail within the test panel. The instrumentation rail includes an optical strain gauge to sense the wheel impact load. The sensed impact data is correlated with wheel damage signatures to identify wheels to be restored or replaced before failure occurs.

摘要： The disclosure relates to a method for radially aligning wheelsets of rail vehicles relative to a coordinate system of a wheelset diagnosis tool and/or wheelset machine tool, which method can be implemented quickly with sufficient precision and comprises the following steps: a) positioning the wheelset at a working position of the tool; b) defining a tool-side coordinate system in an assumed wheel centre point of each wheel, where an X-axis adopts a vertical extent, a Y-axis adopts a horizontal extent and a Z-axis describes the resulting depth extent of the wheel; c) measuring the distance of the wheel backs with respect to one another and defining the Z-position=0 on each wheel back; d) defining a unique Z-position for each measuring point; e) positioning each measuring sensor at the specified Z-position; f) measuring the X-position of each measuring point; g) aligning the wheelset by vertically displacing one of the wheels in order to match the X-positions of the measuring points of two wheels.
