Abstract

A system (10) for providing rail wheel truing recommendations based on rail wheel measurements includes an input device (11) for inputting information into the system. The system also includes a processor (12) receiving measured rail wheel dimensions (14) for respective wheels of a rail vehicle from the input device and a memory (16) in communication with the processor for storing a rule base (18) comprising rules for performing rail wheel truing. The system further includes logic (20) executable by the processor for accessing the rule base stored in memory, for identifying wheels requiring truing according to the rules in the rule base, and for making wheel truing recommendations according to the rules in the rule base.

Claims

1. A system for providing rail wheel truing recommendations based on rail wheel measurements comprising:

an input device for receiving measured rail wheel dimensions for respective wheels of a rail vehicle;

a processor receiving the measured rail wheel dimensions from the input device;

a memory in communication with the processor for storing a rule base comprising rules for performing rail wheel truing; and

logic executable by the processor for accessing the rule base stored in memory, for identifying wheels requiring truing according to the rules in the rule base and the measured rail wheel dimensions, and for making wheel truing recommendations according to the rules in the rule base.

2. The system of claim 1, wherein the rules comprise predetermined dimension limits for the wheels.

3. The system of claim 1, wherein the rules comprise predetermined dimension limits for wheels of axles having shims.

4. The system of claim 1, wherein the rules comprise predetermined wheel dimension difference limits among wheels of a truck of the rail vehicle.

5. The system of claim 1, wherein the rules comprise predetermined wheel dimension difference limits among wheels of a truck of the rail vehicle wherein at least one axle of the truck includes shims.

6. The system of claim 1, wherein the rules comprise predetermined wheel dimension difference limits among wheels of a plurality of trucks of the rail vehicle.

7. The system of claim 1, further comprising a display for displaying wheel truing recommendations.

8. A method for automatically providing rail wheel truing recommendations based on rail wheel measurements comprising:

receiving measured rail wheel dimensions for wheels of a rail vehicle;

automatically identifying ones of the wheels exceeding predetermined dimension limits for the wheels; and

automatically providing wheel truing recommendations for servicing the wheels of the rail vehicle to bring the identified ones of the wheels within the predetermined dimension limits and to maintain the wheels of the rail vehicle within predetermined dimension difference limits among the wheels.

9. The method of claim 8, further comprising providing a truing recommendation for a wheel responsive to a shim being associated with the wheel.

10. The method of claim 8, wherein providing wheel truing recommendations comprises providing a machining recommendation for a wheel.

11. The method of claim 8, wherein providing wheel truing recommendations comprises providing a shim recommendation for a wheel.

12. The method of claim 8, further comprising receiving a wheel defect type.

13. The method of claim 12, further comprising receiving a wheel defect depth.

14. The method of claim 8, wherein the predetermined limits are Federal Railroad Association railroad wheel dimension limits.

15. The method of claim 8, further comprising:

receiving historical wheel truing activities; and

providing wheel truing recommendations based on the received historical data.

16. The method of claim 8, further comprising automatically recognizing when a wheel cannot be trued without exceeding a dimension limit.

17. The method of claim 8, further comprising automatically recognizing when a wheel servicing recommendation for a first dimension would exceed a limit for a second dimension of the wheel.

18. An interactive graphical user interface for automatically providing rail wheel truing recommendations based on rail wheel measurements of a rail vehicle, comprising:

a wheel condition window for interactively displaying measured wheel dimensions and observed wheel defects for wheels of a rail vehicle and for automatically identifying ones of the wheels exceeding predetermined dimension limits for the wheels; and

a wheel truing window for automatically determining wheel truing recommendations for servicing the wheels of the rail vehicle to bring the identified ones of the wheels within predetermined dimension limits and to maintain the wheels of the rail vehicle within predetermined dimension difference limits among the wheels and for interactively displaying the wheel truing recommendations.

19. The graphical user interface of claim 18, further comprising a wheel anomaly window for displaying ones of the wheels of a rail vehicle being identified as exceeding predetermined dimension limits for the wheels.

20. The graphical user interface of claim 18, further comprising a truing recommendation window for displaying wheel machining recommendations.

21. The graphical user interface of claim 18, wherein the wheel truing window further comprises an interactive shim selection section for allowing a user to select and deselect use of a shim and for displaying an effect on a wheel truing recommendation responsive to a shim selection to allow a user to interactively determine a truing scheme among wheels of the rail vehicle.

22. The graphical user interface of claim 18, wherein the wheel condition window further comprises a verified reference groove section.

23. The graphical user interface of claim 18, wherein the wheel condition window further comprises a wheel defect input section.

24. The graphical user Interface of claim 18, wherein the wheel condition window further comprises a wheel defect depth input section.

25. The graphical user interface of claim 18, wherein the wheel truing window, further comprises a proposed first machining loss section identifying a machining loss to bring an identified wheel within dimension limits.

26. The graphical user interface of claim 25, wherein the wheel truing window further comprises a proposed second machining loss section to identify a machining loss to bring wheels of a truck within dimension difference limits for the truck as a result of a proposed first loss machining.

27. The graphical user interface of claim 26, wherein the wheel truing window further comprises a proposed third machining loss section identifying a machining loss to bring wheels of the rail vehicle within dimension difference limits for the rail vehicle as a result of a proposed second loss machining.
