The most imporant part of my thesis is related to Slip/Slide control of the bogie wheels. I have decided to leave out the Tracion Simulator because it does not provide control of the bogie wheels that follow when the locomotives goes on a bend. The traction simulator only provide proof of slipping and sliding when the bogie wheel goes through oil, sand and ice.
Instead I have set up aprocedure for each bogie wheel when there is a bend in the railway line.
I was expelled from Queensland Univesity of Technology without notice when Prof. Ledgwich retired.
I am now working with Engineering Institure if Technology in Perth and receiving a lot more support.
Can you maybe clarify what you mean, as bogie wheels should not need different control when going around a bend - the wheels on the solid axle are conical for that reason. Unless you're referring to the resultant small delta in effective wheel diameter that occurs - but I wouldn't think that it would require major control system intervention. Wheel spinning occurs when the tractive effort exceeds the adhesive friction limits, and wheel sliding/slipping occurs when the braking force exceeds the adhesive friction limits. Maybe explain your question with a little more detail?
Gideon, your name sounds as if you come from South Africa where I come from. I am not with QUT. They expelled me without notice when Prof Ledwich retired. I am now working with Engienner Institute of Technology in Perth Aistralia.
- I have been in the rail business for 55 years and i can assure you that the bogie wheels wear differently according to where they are situated in the bogie. Replaceing of the bogie wheels with axles is required evey three years. If you send me you email address I will forward the technical description about bogie control. [email protected]
