Random loads (PSD) + Static Loads (inertial acceleration)

j.marotta over 4 years ago

Hello,

I'm concerning with Random analysis using either MSC Random Tool either Nastran.

I have a PSD table (Hz vs g^2/Hz) on wich I need to superimpose a static load expressed in g.

So I have a random "load" plus a static load, how can I evaluate their effects when acting together?

Thank you

Use first subcase as static subcase and in subsequent subcase use STATSUB(PRELOAD)=1
