摘要：

Continuous operation of rotating machinery with a rotor crack is a risk condition since the rotor crack grows rapidly and may fail causing a catastrophic accident. This paper develops the finite element model of the rotating shaft with an open crack. The natural frequencies and the resonance curves of such a rotor system with an open crack is investigated, and the concise and accurate modeling of the open crack element is discussed. The natural frequencies and the resonance curves of the experimental system are measured for various positions and depths of the open crack. By comparing both the theoretical and experimental results, the accuracy of the developed simple finite element model of the rotating shaft with an open crack is clarified
