curve conversion
(OP)
I've been given the enclosed vibration curve. I'm not accustomed to seeing double amplitude vs frequency. Is there a way to convert this to PSD vs frequency?
thanks,

It's backwards (acceleration to displacement) but I would think you could go in reverse.

RE: curve conversion
PSD tests are for random vibration where a broadband of excitation frequencies occur simultaneously.
There is no method to directly convert from sine sweep to PSD or vice versa. This can be done indirectly, however, using vibration or fatigue damage spectrum methods. These methods assume that the base input is applied to a single-degree-of-freedom (SDOF) system. Each method determines the response of the system to the given base input.

and thank you Brian for that info as well.
