it is in btween a an SUV and Pick Up. The nuber I gave is an arbitrary number. I wnated to know, how to fix the vertical bending stiffness target? what is the theory or justification for fixing a particular target nuber.

Thanks for the information. But, I wnated to know, how do we get the individual bracketry stiffnesses measured during the test. What boundary conditions they use for testing.
Also, another question is suppose if we want the bending stiffness of BIW or frame to be say around 4000 N/mm, what is...
Hallo!
can anybody tell me how an automotive frame (SUV or pickup)
tested for static stiffness? Can we simulate this in FEA? If so, what boundary conditions we have to use to get the FEA results close to real time testing.

Let me be more clear. My intention is to find the equivalent static stiffness at '0'Hz. displacements are my outputs from the analysis. (SOL111). I am finidng the static stiffness only without constraining the frame

Hallo! all
when we look at the stresses in a component, generally we ignore the stresses at the bolt hole locations. The reason for this is the way we model, the bolt hole(with RBE2's). My question is how do we judge the stresses around the bolt holes? In some cases we may not ignore them!!!
Hallo!
I am running point mobility to find out the '0' Hz equivalnet static stiffness of bracketry of a typical SUV frame.Calculating the deflections and from deflections calculating the stiffness. Aim is to find out the equivalent static stiffness in a free-free conditions. But, I do nothave...
Hi,
can anybody expalin me what is a flex mode in modal analysis? What is the significance of low frequency modes of an automotive frame/cradle?
Thanks

Hallo!
Can any body explain me waht the following load cases stands for
1) 30 mph Chuckhole Vertical(Aft/Right)
2) Curb Island LF Vertical
3)Forward Wide Open Throttle
4)Forward Panic Bracking and
5) 73 degree SEPH LF Impact
Hallo!
Can anybody explain me what is Point Mobility ? and What is a Transfer function?
What is the relation between these two ?
The resons I am asking these questions are I have to run point mobility analysis for an engine mount bracket which is coming on to a cradle.

Hallo!
Can any body explain me how to check the mesh convergence.
i.e, How we can decide whether the FE mesh of 100 or 200 elements will yield correct results? Is there any criteria to decide the number of elements in a FE Mesh
Hi, Can any body explain me or suggest me a web site on
How to do the Conatct analysis? Any material available for an easy understanding about contacts. I wnated to do crash simulation of automotive frames.
