Shock response spectrum analysis
Shock response spectrum analysis
(OP)
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

RE: Shock response spectrum analysis
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.
