Hi guys,
I am quite new with random vibration, I have been reading some material but everything is kind of a mess in my head. It would be great if you can help me with some questions or recommend me a relevant book, thank you.
If I have a plate subjected to a random excitation PSD (eg 0.1 g^2/Hz), what does it really mean? Should I treat it like a forced vibration problem or a base excitation problem?
If the plate has one support leg at each corner, they are not bonded but in contact due to a pretension force at the center of plate, is there any way that I can tell if they will stay in contact? I am thinking if the RMS displacement value calculated from response PSD is less than the displacement introduced by pretension force, they will stay in contact within 68% of time. Is that true?
Thank you in advance.
