A finite element model is used for flexural vibration analysis of a static (non-rotating) rotor with two open cracks, and the stiffness matrices of the cracked elements are obtained using transfer matrix analysis and local flexibility theorem. Through numerical simulation, the effects of the slenderness ratio and the crack depth on the mode shapes and the changes in the eigenfrequencies of the cracked rotor are investigated, and the ratios of the changes in the first two eigenfrequencies are discussed for rotors with shallow cracks. The variations of the changes in eigenfrequencies with crack location are studied. Numerical results obtained are helpful for identification of cracked rotor.
