16.1.18. Rotordynamics Controls

The controls of the Rotordynamics Controls group vary based on the type of analysis being performed. Supported analysis types include:

Coupled Field Static Analysis[8]

The Coriolis Effect property is the only Rotordynamics Controls property for a Coupled Field Static analysis. Options include Off (default) and On, Rotating Reference Frame.

Coupled Field Modal[8], Prestressed Coupled Field Modal, and Modal Analyses[8]

The following properties control the items that apply to a rotating structure:

  • Coriolis Effect: Options for this property include Off (default), On, Stationary Reference Frame for a Modal analysis, and On, Rotating Reference Frame for a Coupled Field Modal analysis (including prestressed). Both of the "On" settings are valid only if the Damped property of the Solver Control category is set to Yes.

  • Campbell Diagram: Set to On if Campbell diagram is to be plotted. The default is Off. On is a valid choice only if Coriolis Effect is turned On.

  • Number of Points: This property is only displayed when Campbell Diagram is set to On. This property’s values indicates the number of solve points for the Campbell Diagram. The default value is 2. A minimum of two (2) solve points is necessary.

    In addition, this value also determines the number of solution Points (data rows) displayed in Tabular Data for the associated Rotational Velocity.

Harmonic Response Analysis

The Coriolis Effect property is the only Rotordynamics Controls property for a Harmonic Response analysis. The default setting is Off. The On, Stationary Reference Frame setting is valid only when the Solution Method is set to Full (the default setting is Mode Superposition). When Coriolis Effect is set to On, Stationary Reference Frame, you can use the Rotating Force boundary condition in your analysis.

Prestressed Coupled Field Harmonic Analysis[8]

The Coriolis Effect property is the only Rotordynamics Controls property for a prestressed Coupled Field Harmonic analysis. Options include Off (default) and On, Rotating Reference Frame.

Static Structural Analysis

The Coriolis Effect property is the only Rotordynamics Controls property for a Static Structural analysis. The default setting is Off.

Note:  For the above analyses, except the coupled field types, when the Coriolis Effect property is active, the application applies Coriolis effects in a stationary reference frame.
