Hello,
I want to study a cantilever beam subjected to a given PSD for a Random Vibration Analysis case study. The given PSD has the form linked in the image above. 
Can anyone suggest me how to represent correctly this spectrum? In particular, will I use TABRND_1 & RANDPS cards for this analysis? In this case, how can I set up these cards with correct numbers and units for reproducing correctly the given spectrum? 
Thanks
