Shock response spectrum analysis

[cavva78]

Dear NX.Nastran/FEMAP users,
I have to perform a SRS analysis, applying a SRS load as follows to an assembly model:

500 Hz -> 500 g
3000 Hz -> 2000 g
10000 Hz -> 2000 g

I have never done that: how do I apply this load to my model? Is there any tutorial or example available?

Thanks

Marco

Hi Marco,
use large mass method. Refer advanced dynamic analysis guide.
use these param cards to specify the shock specturm


param,scrspec,0
param,option,xxxxxx
dti,specsel,0
dit,specsel,1,,A,tableid,,0.05


i hope this helps.
