Wheel / Rail Contact Characterization Program

About the project (Qt6 GUI update in progress)

The software capabilities focus on the characterization of wheel-rail rigid contact through the aid of following specific calculations:

• Potential wheel-rail contact points detection.
• Contact angle tan(γa).
• Rolling-radius difference ∆r function.
• Equivalent conicity tan(γc)=f(λ).

Personal thoughts

• Why C++?: std library is actually powerful, perhaps the most (I still like Java, as well).

• Why this repo?: to provide an example of a coded solution to a real engineering problem.

• Ok, and what else?: it's also an excellent hands-on opportunity to get to work on modern std library.

  💪 don't let anyone get you down 💪
