Engineering solution
Gas-bearing rotor dynamics with the bearing state attached.
Carry defined support coefficients into the rotor model with their operating point, coordinate basis, provenance and applicability boundary intact.
The engineering question
What machine-level consequence follows from the selected gas-bearing state at the required speed and load?
Inputs
- Rotor geometry and material data
- Mass and inertia distribution
- Support positions and orientation
- Bearing stiffness and damping state
- Operating speed range
- Unbalance or excitation basis
Outputs
- Natural and critical-speed families
- Campbell and separation screening
- Synchronous response where scoped
- Stability or damping indicators where supported
- Decision and evidence boundary
Decision boundary
A rotor screen is only as strong as the bearing coefficients and model basis supplied. Screening results do not replace a full validated rotordynamic programme when release authority requires it.
Typical commercial route
Use the Feasibility Screen for one defined machine consequence. Use the AURA Pilot or Evidence Review when coefficient provenance, coupling maturity or validation basis is the main issue.
Bring one defined requirement.
Start with a non-confidential fit check.
