Rotordynamic Analysis of Theoretical Models and Experimental Systems

<p>This thesis is intended to provide fundamental information for the construction and</p> <p>analysis of rotordynamic theoretical models, and their comparison the experimental</p> <p>systems. Finite Element Method (FEM) is used to construct models using Timoshenko</p> <p>beam elements with viscous and hysteretic internal damping. Eigenvalues</p> <p>and eigenvectors of state space equations are used to perform stability analysis, produce</p> <p>critical speed maps, and visualize mode shapes. Frequency domain analysis</p> <p>of theoretical models is used to provide Bode diagrams and in experimental data</p> <p>full spectrum cascade plots. Experimental and theoretical model analyses are used</p> <p>to optimize the control algorithm for an Active Magnetic Bearing on an overhung</p> <p>rotor.</p>
