Random Vibration

Random vibration is one of the most common dynamic environments encountered during launch. It is used to represent a statistically distributed vibration environment often applied as a Power Spectral Density (PSD) in all three axes.

What This Section Will Cover:

• Understanding PSD and GRMS
• Converting acceleration levels to shock response spectra
• Applying random loads in FEM
• Common test specs (NASA, SpaceX, AIAA)

More to come with Python scripts, Nastran examples, and test correlation techniques.
