Hello everyone,
I am trying to simulate the accumulated deformation after several cycles (passage of a train) in a railway track.
My idea is that, after each cycle, the vertical permanent deformation is calculated using an empirical equation. Then, at the end of the cycle, the vertical...
Hi,
I'm trying to model a 2D model of a railway track but I have encountered a problem.
Basically, my model is made of:
- the ground: with 9 sublayers
- the ballast
- the sleepers
- the rail pads
- the rail
- and the train
I'm doing a dynamic analysis, in which the only load is the gravitational...
Hello,
I am doing a calibration of a 2D model using a 3D model as a reference.
Basically, I am applying a surface pressure to the 3D model and then applying the
same pressure to the 2D model. The question is (probably is a dumb question)
if in the 2D model id 400 kPa the pressure and it is...
Hello!
I am doing a simple model: a moving load along a simply supported beam as depicted in the figure below
Basically, I've modeled the moving load as a load applied at a reference point and then used a boundary conditions in order to move it.
The model works. The problem is that I...
Hello, I would like to ask, if you have time, to help me to solve a simple model problem in ABAQUS.
I’m trying to model a simple supported beam subjected to moving sprung mass. This should represent the movement of a train travelling over a rail with constant speed v. The rail is modeled as a...
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...
