Abstract
A bearing and damping structure of a foil bearing is provided. The bearing and damping structure includes interleaved spring plates and damper plates. Each spring plate includes an annular array of fingers to support a foil body of the foil bearing against radially-directed compressive forces. Friction induced between each damper plate and neighboring spring plates causes the fingers of the neighboring spring plates to resist deformation due to the radially-directed compressive forces for damping.
