I have a steady state acceleration signal with acceleration amplitude different frequency with different phase angle.

for example

Frequency amplitude phase

60Hz 60 179

120Hz 70 120

these are fictitious value I have given as an example

1. I wanted to know how to analyze phase angle got from an fft .As the graph is given figure below ?

2. As a whole I want to know how can I represent a time domain acceleration signal accurately in frequency domain. and apply in ansys?

3. how to account for phase lag due to damping?
