摘要： A state monitoring device for a plate spring mounted on a railcar bogie is configured to monitor a state of the plate spring, the plate spring including fiber-reinforced resin containing electrically conductive reinforced fibers containing reinforced fibers extending in a longitudinal direction of the plate spring. The state monitoring device includes: an electrode pair provided at both width direction side end surfaces of the plate spring and sandwiching the plate spring, a width direction of the plate spring being perpendicular to the longitudinal direction of the plate spring and a thickness direction of the plate spring; and a measuring unit electrically connected to the electrode pair and configured to measure an electrical characteristic of the plate spring.

摘要： A displacement detecting apparatus is provided with a self-position detector for detecting a position and an orientation of the apparatus relative to a preset reference position and a preset reference orientation. Displacement of a rail at an upper surface reference point and a side surface reference point relative to a preset reference position is calculated from imaged image data of the surfaces of the rail using an optical cutting method, and the calculated displacement of the rail is corrected using data obtained from the self-position detector, thereby compensating for errors caused by differences in position and orientation of the apparatus associated with a vehicle running motion. By doing so, the displacement detecting apparatus is superior in maintenance and unlikely to cause measurement errors.

摘要： A temperature sensor unit-equipped axle box device of a railcar bogie includes: an axle box accommodating a bearing supporting an axle; a temperature sensor unit attached to the axle box and configured to detect a temperature of an outer ring of the bearing; and an elastic body configured to bias the temperature sensor unit in such a direction that the temperature sensor unit is pressed against the outer ring. The elastic body is elastically deformable so as to follow displacement of the temperature sensor unit around a rotation axis of the bearing.

摘要： There is provided a configuration in which an association between a location of each brake shoe of a railway vehicle and each abrasion detection tag is easily learned, and system implementation and management are simplified. A brake shoe abrasion detection system of a railway vehicle includes a computer that receives data of a signal read by a reader from at least one abrasion detection RF tag attached to each of a plurality of brake shoes of the railway vehicle passing the reader. The computer determines an association between a plurality of the signals and the plurality of brake shoes based on an order that the reader reads the plurality of signals from a plurality of the abrasion detection RF tags attached to the plurality of brake shoes, respectively.
