摘要： Provided is an abnormality detection method for a vehicle body tilt control device that makes it possible to determine which air spring has an air supply/exhaust abnormality. The present invention includes a model creation step for preparing a state estimation model for each of the front and rear vehicle halves 10 into which a vehicle is divided, and an abnormality detection step for applying a state estimation technique to the state estimation model to detect which one of the air springs 3 has an air supply/exhaust abnormality. The state estimation model is a model where, when flow rate command values for air supplied to/exhausted from the air springs included in each vehicle half are input, each of the input flow rate command values for air supplied to/exhausted from the air springs 3 is multiplied by a virtual gain and the results are averaged, and, based on the averages, the average of the heights of the air springs is output, where each virtual gain is included as a state variable.

摘要： Control of vehicle body tilting when a railway vehicle travels along a curve includes: detecting the pressure of compressed air in an air tank; driving a compressor that supplies compressed air to the air tank when detecting a pressure drop in the air tank to or below a first threshold level P 1 in association with introduction of compressed air into air springs; and limiting the amount of compressed air to be introduced from the air tank into the air springs to a level equal to or lower than the amount of compressed air to be supplied from the compressor to the air tank while continuing the introduction from the air tank into the air springs so as to ensure that the air tank pressure is maintained at a level equal to or higher than a minimum level required for braking actuation of the railway vehicle. Consequently, a deterioration in ride comfort can be inhibited when traveling along a curve without causing trouble with braking actuation.

摘要： Provided is a vehicle body height adjustment valve that includes an actuating shaft rotating in response to a variation in the height of an air spring, and performs a pressurized air supplying or discharging operation on the air spring in response to the rotation of the actuating shaft, so as to adjust the height of the vehicle body at a constant height, the vehicle body height adjustment valve including a resolver that detects the height of the air spring so that the vehicle body is tilted when the railway vehicle travels along a curve; wherein the resolver includes a rotor that is fixed to the actuating shaft and a stator that surrounds the rotor, in which an inner circumferential surface of the stator is provided with a plurality of iron cores having excitation coils and detection coils that are wound therearound and arranged in a circumferential direction so as to face an outer circumferential surface of the rotor, and in which an outer peripheral profile of the rotor is configured such that a gap between the outer circumferential surface of the rotor and each iron core of the stator changes periodically in a circumferential direction during a 360-degree rotation of the rotor. The vehicle body height adjustment valve having a resolver for a railway vehicle with such a configuration can realize reductions of cost and size.

摘要： An inspection apparatus (800) calculates an alignment irregularity amount by substituting angular displacements of wheel sets (13a to 13d) in a yawing direction, state variables derived by a filter, and a measured value of a forward-and-backward-direction force into motion equations that describe yawings of the wheel sets (13a to 13d).

摘要： OBJECT: To accurately detect a derailment, so as to prevent a railway vehicle from traveling when its wheels have become disengaged from a rail without an operator being aware of it, thus improving safety after the derailment occurs.
MEANS: For example, a transmission line 5 configured to be broken when it comes into contact with a rail 4 is installed on a disengagement prevention guide 1 attached to an axle box 3 of a railway vehicle. One end 5a and the other end 5b of the transmission line 5 are connected to a determination unit 6 to monitor continuity of the transmission line 5. In the event of a derailment, the determination unit 6 determines that a derailment has occurred when the disengagement prevention guide 1 makes contact with the rail 4 and the transmission line 5 breaks, thereby interrupting the continuity of the transmission line 5.
