RMS results are at 1 standard deviation. PSD results are at particular frequecy.
As per my knowledge calculating the stress as per your calculations may be wrong. This is just my opinion.
kindly go through the Lesson 4 i.e. random vibration analysis of a shipboard cabinet according to MIL-STD-810F from the solidworks simulation dynamics manual.
Ameer - Can you post a PDF of the lesson you refer to?
Hi Rick N,
