- Use the case as a first-approximation design direction.
- Proceed to detailed CAD/CAE and controlled geometry definition.
- Identify the next validation evidence required.
- Compare the operating point with the first critical family.
Illustrative public Architecture Screen sample · AURA-PS-J15-20K
What an Architecture Screen decision package looks like.
This sample uses an existing public controlled case to show report structure. It is not a fictional customer project and it does not increase the evidence authority of the underlying case.
01QuestionIs the controlled bearing–shaft state separated sufficiently from the first critical family?
02Controlled statePublic AURA-PS-J15-20K operating state and attached support coefficients.
03Decision todayPhysical screen PASS; release authority remains SCREENING ONLY.
04Required next proofFreeze detailed geometry and add decision-critical CFD / FE / test evidence before release.
2 · Controlled basis
Input state carried with the result.

Radial clearance30µm

A customer package would also record coordinate basis, gas state, load basis, geometry revision, assumptions, supplied evidence and agreed exclusions.
3 · Bearing result
Calculated support coefficients at the stated operating point.
Kxx39.18 N/µm
Kxy+10.26 N/µm
Kyx−10.26 N/µm
Kyy39.18 N/µm
These coefficients are presented as state-dependent engineering outputs, not portable material properties. Their meaning depends on the attached geometry, clearance, pressure, coordinate convention and method basis.
4 · Rotor consequence
The selected support state is carried into the machine-level screen.
Operating speed20,000rpm
First critical family29,780rpm
Separation margin48.9%relative to operating speed
Physical screenPASSfor the controlled case
The value of the package is the connected chain: bearing state → rotor model → physical consequence → evidence-bounded decision.
5 · Decision basis
What this result may and may not support.
Not supported now
- Final manufacturing release.
- Universal performance guarantee.
- Transfer of coefficients to a different operating state.
- Replacement of detailed thermal, structural or experimental validation.
Why the sample remains SCREENING ONLY
The boundary is methodological, not cosmetic. Open the stop-boundary map to see which evidence gaps prevent screening from being promoted into release authority.
Open evidence-boundary map →6 · Required next action
Convert the screening result into higher-authority engineering evidence.
- Freeze the detailed geometry and coordinate basis.
- Confirm thermal state, tolerances and gas-supply assumptions.
- Run detailed CAD/CAE/CFD where the uncertainty justifies it.
- Attach measurement or test evidence to the decision-critical claims.
- Re-run the connected bearing-and-rotor decision at the controlled release state.
Turn the required next action into a controlled evidence task.
The operating-state evidence map defines the question, target proof, acceptance quantity and re-coupling rule before detailed work starts.
