Random Vibration for Wing

  I'm conducting a random vibration analysis on a fixed-wing VTOL model aircraft to measure the amount of vibration exerted towards the wing during flight process. However, I don't have any data for the Input PSD (displacement, accelaration, or velocity). How could I proceed with the Random Analysis? Or do I need to use different analysis system? I'm new to Ansys so I appreciate any suggestions. Thank you.
  Below are the geometry of the wing.

  Hi Danial,
  For performing random vibration analysis, yes, you need input PSD data. If you have force or displacement acting on your model, then you can perform the harmonic response analysis.
