Summary: | Propagating fatigue cracks can have detrimental effects on the reliability of the rotating machinery such as turbomachinery, process machinery, etc. Dynamic analysis of cracked rotors has been a subject of great interest for the last three decades and excellent reviews on this are available in Refs. [1-4]. All the works reported in Refs. [1-4] consider mainly the transverse crack that occurs from the fatigue of the shaft material due to an excessive bending moment. However, Ichimonji and Watanabe [5] considered a slant crack that occurs from the fatigue of the shaft due to the torsional moment, and studied the dynamics of a simple rotor for qualitative analysis. Ichimonji et al. [6] extended their work and presented using 3D finite element method (FEM), a qualitative analysis for the rotor with slant crack. Sekhar and Balaji [7] have developed the stiffness matrix of an element having slant crack and using FEM, analyzed the rotor system for steady-state response. Further studies on slant cracked rotor system are available on condition monitoring in Ref. [8] and on transient analysis in Ref. [9]. |
