Simpe Winkler Beam Foundation Model
Simpe Winkler Beam Foundation Model
(OP)
Hello! I am new to ABAQUS and I have trouble to model a simple problem.
I have to model a rail on an elastic foundation with BOEF model: the rail is a beam and is above a series of springs that model the sleepers, ballast,etc.
My model consists in:
- 1 beam of 10 meters (the rail), modeled as a 2D wire
- springs at each 600 mm
- 1 load at the midpoint of the beam
- 2 boundary conditions at the extremity of the beam to fix U1 and U2

I have done the model but it seems that it does not recognize the springs.
I modeled the springs using "connect points to groun (Standard)".

What could be the problem? I attached the cae file. I hope you can see it.
Thank you

RE: Simpe Winkler Beam Foundation Model
Or if you are familiar with keywords, can use keywords to define the springs like this:
*Spring, elset=springs
1
2.322e+06
*Element, type=springs
1, Spool-1.5
2, Spool-1.6

I've partitioned the beam in the points in which I want the springs

The problem is that when I want to create the springs (from "Springs/Dashpot") it requires 2 nodes.
I have the nodes in the beam, but how can I create the other nodes (ground nodes?).

It seems that the springs dont act.
