摘要： A system that includes a detection device, an imaging device, and a control device is disclosed. The detection device may generate proximity data relating to a proximity of an undercarriage of a rail vehicle, and the imaging device may capture one or more thermal images of the undercarriage. The control device may receive a first thermal image and a second thermal image of the undercarriage. The first thermal image may be captured using a first integration time, and the second thermal image may be captured using a second integration time. The control device may determine composite thermal data associated with the undercarriage. The composite thermal data may include information mapping a first range of thermal data and mapping a second range of thermal data to one or more components of the undercarriage. The control device may cause an action to be performed in connection with the composite thermal data.

摘要： The invention relates to a method that can be used in the field of rail systems technology to detect the flat wheel deformation (31) condition in the wheels (30) of the railway vehicle (20). In particular, the invention is concerned with the detection and analysis of the mechanical vibrations, generated by the vibration waves (50) from the wheels (30) moving on the rails (10) with the vibration sensors (40). Hence, it relates to the method for determining the presence and severity of the flat wheel deformation (31) condition in the wheels (30) of the railway vehicle (20).

摘要： According to one embodiment, an inspection system of an embodiment is an inspection system for inspecting a bogie including a plurality of side beams extending in a front-rear direction and disposed apart from each other in a left-right direction and a cross beam connecting the plurality of side beams. The inspection system includes one or more sensors and a position locator. The one or more sensors are installed on at least one of the plurality of side beams and the cross beam and detect elastic waves. The position locator identifies a beam in which the elastic waves have been generated or locates a position of an elastic wave source on the basis of the elastic waves detected by the one or more sensors.

摘要： Methods are provided that may include determining one or more of a vibration characteristic or a fluid characteristic of one or more components of a vehicle and determining one or more expected characteristics for the one or more of the vibration characteristic or the fluid characteristic. The methods may also include determining whether the one or more of the vibration characteristic or the fluid characteristic deviates from the one or more expected respective characteristics, and implementing one or more responsive actions in response to determining that the one or more of the vibration characteristic or the fluid characteristic deviates from the one or more expected characteristics.

摘要： An abrasion inspection apparatus includes: a first imaging unit that is installed on a side of a track, a vehicle traveling along the track, a guide wheel being installed on a side of the vehicle, the first imaging unit imaging an inside of the track via a telecentric lens; a second imaging unit that is installed in a vehicle traveling direction with respect to the first imaging unit on the side of the track and images the inside of the track via a telecentric lens; an image acquisition unit that acquires an image which is an image of a boundary of the guide wheel captured by the first imaging unit and is an image of a boundary on a first direction side in the vehicle traveling direction and an image which is an image of the boundary of the guide wheel captured by the second imaging unit at the same time as the capturing of the image by the first imaging unit and is an image of a boundary on an opposite side to the first direction side; and a guide wheel detection unit that detects an abrasion situation of the guide wheel according to a position of a boundary indicated in the images acquired by the image acquisition unit.

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.

摘要： The invention relates to a method for testing of a train wheel by ultrasound. The method is based on a pulsed ultrasonic field in the train wheel to be tested by an array of individually controllable ultrasonic transmitting transducers acoustically coupled to the train wheel each controlled with a specific analog transient excitation signal. Each analog transient excitation signal generated based on an ultrasonic transmitting transducer-specific stored digital transient excitation function. The resulting echo signals from the train wheel to be tested are recorded by an array of individually controllable ultrasonic receiving transducers. Each ultrasonic receiving transducer can provide an analog, time-resolved echo signal. The received echo signals can be digitized in a transducer-specific way and stored in a set. A plurality of different reception processing rules can then be applied to the latter. Furthermore, the invention relates to a device for carrying out the method.
