I'd say the original assumption is pretty good for most purposes. Let's proceed based on the assumption. In that case: 1X vibration alone => linear system response to assumed sinusoidal unbalance excitation force. 1X + harmonics => non-linear system response to assumed sinusoidal excitation force. Typically looseness.
