Base Motion

Base Motion

Base Motion

(OP)
Hello everybody:

I'm working with a base motion, exactly with an harmonic and non harmonic excitation, the input in the harmonic motion is assumed by a displacement, and I found the response, but I think it was just coincidence because I don't know what's the importance in the relation between the frequency extraction results and the frequency output results. I know it have an important relation, because I proved with different relative frequencies and the result appears different...very different

Does anybody have experience with base motion?
