GFB Analysis of Gas Foil bearings
The GFB codes calculate
the static and dynamic force performance of radial foil bearings (bump-type)
|
Bump-type foil bearing |
1)
bearing drag torque & power dissipation, Only codes benchmarked to experimental
data. See publications |

XLGFB1D |
$5,000 |
Simple
model of GFB w/o accounting for bending of top foil (useful for quick
estimations of performance( |
|
XLGFBpress |
$9,000 |
GFB
with top foil model and side pressurization and including preloads (shims).
Useful for those really interested in applying GFBs to rotating machinery. |
|
XLGFBTHD |
$15,000 |
+
Thermal effects, including materials expansion, etc. (The whole nine-yards).
Useful for high temperature applications such as in (micro) gas turbines and
turbochargers. Sponsored by

Analysis: gas film
Reynolds equation for hydrodynamic pressure generation + finite element model
of top foil and discrete structural model for underspring elements (bump
foils). THD version includes thermal energy transport (thermal management)
including growth of components with temperature and rotational speed.
