摘要:
A track brake control system for providing braking of a railway vehicle is disclosed. The control system operates upon receipt of an emergency braking command. The control system includes a member for receiving deceleration information from one or more sensing devices. The control system further includes member for comparing the deceleration information with a reference value or reference profile. Further, the control system includes at feast one regulating device for continuously adjusting a braking demand signal to a track brake so as to cause deceleration of the railway vehicle based on the this comparison.
摘要:
A wheel (1) of a railway vehicle is associated with a vibration sensor (3) for supplying a vibration impulsive signal (V), indicative of the vibration of the wheel, to an electronic processing unit (E). This generates, based on the vibration signal (V), an impulsive surveillance signal (S) the instant value of which is increased in a manner correlated to the amplitude of each vibration impulse (I) and decreased in accordance with a predetermined law after each vibration impulse. The processing unit (E) compares the instant value of the surveillance signal (S) with a reference threshold value (T) and automatically generates an alarm signal (A) when the instant value of the surveillance signal (S) reaches or exceeds the reference threshold value (T).
摘要:
A method for detecting the velocity (v) of a railroad car (1) and a vertical acceleration (a) that occurs at the portion of a car body (2) above a spring device (6) of a bogie (3) while the car (1) is running on a track, and also extracting a component of the vertical acceleration (a) in a predetermined frequency range. The method decides that the car (1) has derailed when the absolute value of the vertical acceleration (a) in this frequency range exceeds a predetermined limit vertical acceleration (al) corresponding to a predetermined velocity (v), or when a vertical displacement (d) calculated by double-integrating the vertical acceleration (a) for each predetermined evaluation time (T) is negative and its absolute value is greater than a reference value (dc).
摘要:
Le dispositif (2) de détection d'obstacle comporte : - une barre de détection (4) destinée à s'étendre transversalement au véhicule et propre à recevoir un impact avec un obstacle, - au moins un assemblage (6) de détection d'un impact, supportant la barre de détection (4) et comprenant : un boîtier (12) destiné à être rapporté sur le véhicule, un levier (14) solidaire de la barre de détection (4) et mobile en rotation par rapport au boîtier (12) autour d'un premier axe (A) parallèle à la barre de détection (4), entre une position de repos et une position d'activation, et un organe élastique (16) de rappel du levier (14) vers sa position de repos. Le dispositif comporte un dispositif (8) de déclenchement activable par le levier en position d'activation. L'assemblage de détection (6) comprend des moyens de réglage (18), propres à appliquer une précontrainte sur l'organe élastique (16).
