static analysis software

[mahdibalali]

Hi everybody

Do you know any software, which can do the static analysis of simple structures?
(I mean to calculate the forces and moments on a structure, knowing the loading and the constraints)

Thanks in advance.

We use NX nastran, which does a finite element analysis. There are some other programs that do the same thing.

There may be simpler (read cheaper) programs to do this, depending on the complexity of your structures.

you could check out the General Engineering Programs[/LINK] part of this forum for more information

NX 7.5
Teamcenter 8

ADAMS

Also SolidWorks Motion (which uses the ADAMS kernel).

ADAMS??

Shurely shome mishtake.

When I used ADAMS it was aimed purely at multibody dynamics, not static analysis of structures. I would have thought any of the bazillions of FE codes would do this job well enough.

It worked for me. I'm sure there's better tools, but it's all I had at the time.

We use SolidWorks Simulation and COMSOL. It all depends on how deep your pockets are.

Solidworks simulation for the simple stuff, ANSYS for more complicated problems.

Question for the OP

A car weighs 2000 lbf. the centre of gravity is exactly on the centreline, and half way between the axles, which are symmetrical etc.

What is the vertical force on each of the 4 wheels?



Cheers

for simple structures you can (should be able to ?) solve them by hand.

complex structures/problems require FEA ... there are many programs available, designed for different applications (buildings, airplanes, mechanisms, ...)

If you mean simple beam models, CalculiX might be a good option for you. It's free, however the GUI interface leaves something to be desired. That said, it seems like it would work great for crunching things like statically indeterminate beam models.

The syntax is identical to that of ABAQUS, which is a top-notch FE package, capable of solving very complex, non-linear problems.

I've used this successfully:

It's only truss members and beam elements (no shells AFAIK), but the variety of constraints is quite comprehensive (deflection/force/thermal).
Linear analysis only.
