FSAE Chassis Anlysis Problem

Hi Every Body
We are first time participate in fsae competitions and have problem in chassis analysis:
First for ease of design we decided to build chassis by baseline materials so as the rules say we don't need to give analysis documentation for our chassis design or send SCRF ,but at the end of design we want to check our chassis by the conditions & forces which the rules determined for giving SCRF at rules it reminded that:
"Load Applied: Fx = 6.0 kN, Fy=5.0 kN, Fz=-9.0 kN
AF4.1.2 Application point: Top of Main Roll Hoop
AF4.1.3 Boundary Condition: Fixed displacement (x,y,z) but not rotation of the bottom nodes of both sides of
the front and main roll hoops.
AF4.1.4 Max Allowable Deflection: 25mm"
so we want to analyze our chassis with COSMOS Works or Ansys How can I add the determined Boundary condition ?
Any picture for better guide will help
Thank to all

Hi, I am Claude. I don't think we got introduced. And you are...?

Claude,
Amin has introduced himself a week or so ago in the 'bodywork' thread.

Amin,
It might be a good idea to add a signature to the bottom of your posts.

Pat, Amin,

Did not notice that. I looked at the profile and there was no info. Worth to put something in the signature .

Hi Farzaneh,

Are you asking about where the boundary conditions need to be added? (bottom nodes of both sides of the FRH and MRH).

Or are you asking how to add boundary conditions in COSMOS Works? I imagine that in COSMOS you have your chassis set up as a collection of simple beam elements, in which case you should be able to specify the restraints applicable at the node/beam ends. Sorry I can't be more specific, I haven't done FEA for a few years.

Sorry Claude!
I Updated My profile today.
thanks for your remind

ya, I have doubt about the options which COSMOS Works has.It has only "Fixed Displacement" , the software did not specified the detail of these conditions (may I don't have clue!) Attachment 235

Give the advanced option (below 'standard') a go. Failing that, try the help files etc. Sorry I couldn't be of more help

Doesn't any body know it?

Hi Farzaneh,

Give this a go (copy/paste the following into youtube): /watch?v=jKnfo6I6zJU

Do you have a local VAR that can assist you?

I'm sure someone on here will have done it, sorry I can't be of more help.

thanks Jay
but I saw all of solidworks simulation on youtube and they don't talk about it directly,I post this problem on solidworks.com/forums it has after 1 day 54 visits but no reply!!Do you know How can I do it in Ansys or Abaqus?

Hi Every Body
I found answer in SolidWorks.com/Forums .Any body want to simulate this boundary condition use "Use Reference Geometry" and add to Transition Tab x=y=z=0 and apply the load .
But this question not replied which I use Baseline material (which doesn't need SCRF and simulation documents) but the simulation shows that the baseline material will fail!!
Any Ideas...?
