DLOAD, Random Response Analysis

Altair Forum User

Hi:

How I can calculate the load I have to apply to Dload 1 and Dload 2 for the Random response analysis?

And What is the Critical damping ratio value recommended for a range of vibrations at 20 from 2000 HZ?

I want analyse a cubesat.

Someone can help me?

Kind regards

This information must be available in structural dynamics texbooks, library, online resources.

I would suggest you to kindly refer our tutorial on Random Analysis which would help you with the set-up. The tutorial is RD-2050.
