Method for detecting vibration in a rail vehicle
View Patent ↗A method for detecting a vibration of a driven axle system of a rail vehicle includes a sensor system detecting a parameter indicating the vibration of an element of the axle system and an evaluating unit evaluating a signal of the sensor system. In order to reliably detect the vibration of the driven axle system of the rail vehicle, the sensor system includes a motion sensor which detects a motion of the element as the parameter.
1. A method for detecting a rotary vibration of a driven axle system of a rail vehicle, the method comprising the following steps:
providing an element as a part of a bogie of the rail vehicle to which a juddering motion of a driven and juddering axle is transferred;
detecting a parameter indicating a vibration of the element of the axle system by using a sensor system;
detecting the parameter as a movement of the element carried out as a rotation by using a motion sensor of the sensor system, and the movement carried out as a rotation being a rotary movement of the bogie; and
evaluating a signal of the sensor system by using an evaluating unit.
2. The method according to claim 1 , which further comprises detecting an acceleration of the element as a parameter by using an acceleration sensor of the sensor system.
3. The method according to claim 1 , wherein the motion sensor is a rotation sensor.
4. The method according to claim 1 , wherein the sensor system, 32 ) includes a sensor of an inertial navigation system.
5. The method according to claim 1 , which further comprises filtering the signal of the sensor system to a frequency band lying about a natural oscillation of the vibration.
6. The method according to claim 1 , which further comprises detecting the vibration from a longitudinal movement and a rotary movement of the element.
7. The method according to claim 1 , which further comprises concluding one of a plurality of types of vibration from signals of a plurality of motion sensors.
8. The method according to claim 1 , which further comprises concluding a place of origin of the vibration from signals of a plurality of motion sensors.
9. The method according to claim 1 , which further comprises concluding a strength of the element from sensor data.
10. A rail vehicle, comprising:
a bogie including a driven axle system having a driven and juddering axle and an element to which a juddering motion of said driven and juddering axle is transferred;
a sensor system for detecting a parameter indicating a rotary vibration of said element of said axle system, said sensor system including a motion sensor, said parameter being movement of said element carried out as a rotation, and said movement carried out as a rotation being a rotary movement of said bogie; and
an evaluating unit for evaluating a signal of said sensor system.
