| Description | Journal: Iop Conference Series: Materials Science and Engineering The aim of this paper is investigating the cracked Jeffcott with an offset disk rotor system. The finite element method (FEM) used in ANSYS gives an attractive approach for modeling the rotor dynamic system. The effect of changing speeds has been analyzed on the dynamic parameters of journal bearings (stiffness and damping) and then on Sommerfeld number. The relation of the dynamic bending stress with the static stress of rotor with cracks (dynamic load factor (DLF)) and with the ratio of depth crack to radius rotor has been established. The results have been obtained numerically by using ANSYS. The results show when crackâs depths increase the DLF increases and reach to maximum when a/R = 0.8. |
