Forced Vibration an overview ScienceDirect Topics

Figure 5 20 shows that for forced vibration the critical frequency remains constant at any shaft speed The critical speeds occur at one half one and two times the rotor speed The effect of damping in forced vibration reduces the amplitude but it does not affect the frequency at which this phenomenon occurs
