What is the Power Spectral Density model for random vibration fatigue?

Hi, physics forum scourers. I am new around here and intend to introduce myself. My name is Nick, I am a Mechanical Engineer for a large multinational corporation. I am interested in moving down an analytical career path and will have many technical discussions to participate in hopefully. Probably more questions than answers but we'll see!

Right now I am interested in understanding the Power Spectral Density model for solving random vibration fatigue. This would be very useful to me, professionally.
