Simulate a rolling contact of a wheel with a rail in abaqus.
Simulate a rolling contact of a wheel with a rail in abaqus.
(OP)
Hello,
I'm a Phd student and i use Abaqus to simulate the rolling of a wheel on the rail. I have a really geometric of a wheel and a rail, and i simulate a sleeper like a material point and it related with a rail with a spring and damper, so in boundary condition i have the vertical translation of the rail and the wheel to simulate the dynamical behavior of wheel and rail.
in the load step a use a combined translation and rotation of the wheel, which is related with a rail by a surface to surface contact.
but after calculation i get i false results and i lose the contact of the two parts, i'm in this problems for some days a go, and until now i don't know the solution so i need your help.
and think you.

I think that i know the cause of the problem, now i try just to apply a concentrated force in the center of the wheel, and i make one step to look the behavior of the wheel without motion.
I get that the vertical displacement of the wheel oscillate, which is not normal.
What do you think the cause of this problem?

For my last simulation, i get a best results than the last time, and you can find here a picture of my model, with the new modifications:
I use Abaqus standard, and two steps, the first for the application of the load, and the second for motion.
The difference of abaqus standard and explicit is that i get more oscillations of the wheel in explicit, and in standard not more.
Can you explain me what is the origin of this oscillations. Normally i need to get a vertical displacement of the wheel with application of the load.
And what is the modifications that i can do to get more interesting results.
Think you.

Did you solve your problem in ABAQUS/explicit?

I am new to abaqus and want to Simulate a rolling contact of a wheel with a rail in abaqus.
Please help me and provide some .cae files, videos and tips so that I shall be able to do it.
