Method for stabilizing a rail vehicle
View Patent ↗In a method for stabilizing a rail vehicle with a wheel set, the speed of the rail vehicle is changed when a critical vibration state of the wheel set occurs. An advantageous state can be achieved if the speed of the rail vehicle is changed by using a vibration state variable of the wheel set.
1. A method for stabilizing a rail vehicle having a wheel set, which comprises the steps of:
changing a speed of the rail vehicle if a critical vibration state of the wheel set occurs;
changing the speed of the rail vehicle using a vibration state variable of the wheel set; and
permanently reducing the speed to a predefined speed value if the critical vibration state of the wheel set occurs repeatedly.
2. The method according to claim 1 , which further comprises using the vibration state variable as a controlled variable for changing the speed.
3. The method according to claim 1 , wherein the vibration state variable is an acceleration running generally perpendicular to a direction of travel of the rail vehicle.
4. The method according to claim 1 , which further comprises determining a maximum speed of the rail vehicle that is different from a changed speed in dependence on the changed speed.
5. The method according to claim 4 , which further comprises determining the maximum speed as the changed speed multiplied by a safety factor.
6. The method according to claim 1 , which further comprises:
reducing the speed;
measuring the vibration state variable during the reducing of the speed; and
reducing the speed until the vibration state variable falls below a predetermined limit value due to the reducing of the speed.
7. The method according to claim 1 , which further comprises changing the speed to a discrete speed value.
8. The method according to claim 1 , which further comprises reducing the speed with a constant deceleration.
9. A method for stabilizing a rail vehicle having a wheel set, which comprises the steps of:
changing a speed of the rail vehicle if a critical vibration state of the wheel set occurs;
changing the speed of the rail vehicle using a vibration state variable of the wheel set; and
only reducing the speed when the critical vibration state of the wheel set occurs above a predetermined minimum speed.
10. The method according to claim 1 , which further comprises changing the speed of the rail vehicle using global positioning satellite information for a current position of the rail vehicle.
11. The method according to claim 1 , which further comprises changing the speed of the rail vehicle using a measuring signal of an on-board track monitoring device.
12. The method according to claim 1 , which further comprises changing a damping of a vibration of the rail vehicle.
13. The method according to claim 1 , wherein the changing in the speed is made functionally dependent on the vibration state variable.
14. The method according to claim 1 , wherein the stabilizing is an attenuation of a lateral vibration of the wheel set of the rail vehicle.
15. The method according to claim 1 , which further comprises incrementally changing the speed to a discrete speed value.
