RODAPre
RODAPre is a preprocessor for RODA (Honeywell's rotor dynamics finite element analysis code). Use ANSYS to read in the IEGS file of a rotor layout. The keypoints of the IGES file are used to graphically define the geometry of the RODA model. The following model components and parameters can be defined and written out to am input file for RODA20.
- Cylindrical beam element
- Tapered beam element
- Cone beam element
- Stations
- Lumped mass stations
- Non-beam mass stations
- Foundation stations
- Support (ground) stations
- Translational stiffness
- Rotational stiffness
- Translational damping
- Rotational damping
- Constraints
- Squeeze film damper
- Rub
- Speed dependent stiffness
- Critical speed control
- Unbalance response control
- Beam spin ratios
- Beam reference beam
- Temperature table
- Beam temperature
- User elements (2x2 and 4x4)
- Beam properties (axial load, beam unbalance, internal damping)
- Beam-grp for mass intertia and energy
