This paper puts forward the problems of rotational vibrations of machineries, presents the analysis of zero-damping vibration and revolving vibration, and gives out the principles of interference graphics. Some method to determine potential breakdown systematically within the real time domain are given out. For concrete structures, it is convenient to predict resonance points with an interference graph, as to prevent the breakdown with rotational machinery effectively.
