railway modeling

(OP)
Hello everyone,
how can i model train load and which step i should use and which amplitude because i want it to be a repeated load
please help

RE: railway modeling

It is impossible to answer that, because your question is very inespecific.

Have you ever used abaqus?
What are you trying to modeling? The wheel-rail? The ground? The whole train?
And... what are you looking for? Fatigue? Vibrations? Static Stresses?

RE: railway modeling

Hey hbkhero. Try pressure load with a periodic amplitude.
