Comparison of Campbell Plots Using Different Rotor Interfaces

Application ID: 102611

Different types of elements can be used for modeling a rotor, depending on the level of complexity and the type of the system being modeled. The modeling steps and representation of the results will vary with the type of idealization. In this tutorial model, an eigenfrequency analysis is performed on a stepped rotor, using three different physics interfaces for rotordynamics: Solid Rotor; Solid Rotor, Fixed Frame; and Beam Rotor. The resulting Campbell plots from these interfaces are compared with each other. The model also helps in understanding the different steps involved when using each interface.

This model example illustrates applications of this type that would nominally be built using the following products:
