Abstract: Disclosed is a railway vehicle with a car and a bogie. The bogie includes a chassis and a secondary suspension system. The secondary suspension system includes a jack and a power supply device of the jack fluidly connected to the jack by at least one flow limiter. The jack is configured to go from a first so-called passive configuration, in which the supply device is inactive, the jack then being able to passively damp the oscillations between the car and the chassis using the flow limiter, to a second so-called active configuration in which the supply device is configured to supply the jack in order to modify the distance between the car and the chassis or in order to keep the distance constant between the car and the chassis.

Abstract: The present invention concerns an insulating joint for electrically insulating a pair of adjacent rail sections of a railway track, each rail section extending along a longitudinal axis and defining at least one connecting surface substantially perpendicular to the longitudinal axis and a plurality of lateral surfaces extending along the longitudinal axis. The insulating joint comprises a joint body having substantially the same cross section as the rail sections and defining two contacting surfaces, each contacting surface being intended to be in contact with the connecting surface of one of the rail sections. The joint body is made from an insulating material comprising a reinforcing structure made of metal or carbon fibers, the reinforcing structure being placed inside of the joint body with a distance from the contacting surfaces.

Abstract: A method including measuring vibrations of a rotating machine during its operation, using a vibration sensor. Next, from the signal measured by the sensor, automatically extracting, using an electronic detection device, a first signal representative of components of a first frequency range of the measured vibration signal, and a second signal representative of a second frequency range of the measured vibration signal. Then, from the first signal, calculating a first data set belonging to a time domain of the first signal, and extracting first calculation elements therefrom. Next, from the second signal, calculating a second data set belonging to a frequency domain of the second signal, and extracting second calculation elements therefrom. Lastly, determining a health index of the bearing from each of the extracted calculation elements.

The health status assessment system has at least one leaf actuated by a kinematic chain including at least one motor having an associated angular position or rotation speed encoder and at least one switch. The health status assessment method includes steps for analyzing at least one actuating cycle of the kinematic chain between a first and a second position wherein,
during one said cycle, information is acquired representative of the electrical energy consumed by the motor, or position or speed information provided by said encoder or binary information indicating positions of switches. The method further includes dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value, and then establishing a health status diagnosis of the health status assessment system.
