In this paper, a two-node beam element (as a simplified modeling approach) has been presented to investigate the vibration characteristic of rotor system with a complicated geometry. The decline of stiffness near the region of discontinuity is investigated on the basis of stain energy, and the conclusion is applied to the 2-node beam element analysis. In addition, the bending critical speeds and corresponding mode shapes of an integral rotor of 1000MW turbine have been investigated as an example. Verification results show that the simplified modeling approach by this 2-node beam element meets the accuracy requirement.
