Abaqus Random Response - PSD definition 1

[RoHun]

Hi everyone,

I want to define "Acc base motion" using PSD signal. I would like to ask, the unit of values that I enter in "PSD Definition" window is in g, g/Hz,or g^2/Hz?

Thanks.

You should provide the tabular data in g^2/Hz. Reference gravity specified above will be used to calculate actual accelerations.
