Cracked Rotors Modeling for Vibration Analysis and Control, Ph.D. Dissertation Sharif University of Technology ; Behzad , Mehdi (Supervisor) ; Meghdari, Ali (Supervisor)
Abstract
The main aim of this thesis is to develop a mathematical model for vibration analysis of cracked rotors. This model should be a simple and precise model for prediction of the cracked rotor vibration behavior and suitable for vibration control. In order to create such model, the pure bending of a cracked beam is analyzed at first. This analysis is performed for two different orientations of the crack with respect to the beam and the bending vector. In this section a continuous bending model with continuous model for crack is developed which can predict the full deformation of the cracked beam in bending and can estimate the stress distribution in the beam with good approximation. Comparison...
