Acceleration spectral Density (ASD) using Simpack

Acceleration spectral Density (ASD) using Simpack

Acceleration spectral Density (ASD) using Simpack

(OP)
Hi all,

I am working on a flexible body model in Simpack in which the aim is to obtain an ASD spectrum curve (ASD vs. Fequency). After performing an offline time integration, when I import the .sbr file in post processor, I am aware of how to make general plots. But, when it comes to ASD, I do not know how to use the proper filter and in which way I need to apply them. For example, after I insert the FFT filter on the acceleration vs. time plot, the x-axis still remains in time (s) instaed of frequency(Hz).

Please do help me on this. Thank you!!
