Hello everybody:
I have been working with a base motion of a simple cantilever beam. I'm studying the relative displacement of this element, but the results are strange. I make an harmonic excitation at the base, and I supposed that the relative response at the tip should be my harmonic excitation with different amplitude and phase angle.The plot shows the harmonic response , but there is another high frequency inside my harmonic excitation.
Does anybody knows how to apply a filter? I want to see just
the excitation frequency in my response
Thank you
