Selecting Physics Interfaces
The Rotordynamics Module contains tools for modeling rotors and bearings. For modeling the rotor, there are three physics interfaces: the Solid Rotor interface; the Solid Rotor, Fixed Frame interface; and the Beam Rotor interface. The basic physics interfaces in the Rotordynamics Module are:
•
Solid Rotor — For modeling the rotor as a 3D object in a corotating frame
•
Solid Rotor, Fixed Frame — For modeling the rotor as a 3D object in a space-fixed frame
•
Beam Rotor — For the abstract modeling of the rotor as a line object with bending stiffness
•
Hydrodynamic Bearing — For modeling hydrodynamic sliding bearings with very small oil film thickness
