Comparison of Campbell Diagrams Using Different Rotor Interfaces

Application ID: 102611


Different types of elements can be used to model a rotor, depending on the complexity and characteristics of the system. The modeling workflow and representation of the results vary with the chosen idealization. In this tutorial model, an eigenfrequency analysis is performed on a stepped rotor using three rotordynamics physics interfaces: Solid Rotor, Rotating Frame; Solid Rotor, Fixed Frame; and Beam Rotor. The resulting Campbell plots are compared across the three interfaces. The model also demonstrates the different modeling steps involved when using each interface.
