Steady State Harmonic Response Analysis

Steady State Harmonic Response Analysis

For steady state harmonic excitation analysis, the excitation is expressed in a general form:

where |Q| is the excitation amplitude and the omega is the excitation frequency. If the excitation frequency coincides with the rotor speed, it is called synchronous excitation. However, the harmonic excitation frequency does not have to be the same as the rotor speed. It can be a multiple or fraction of the rotor speed, or completely independent from the rotor speed. The response is also a harmonic motion with the form:
