Abstract
A bearing support assembly to support one or more bearings on a shaft. The bearing support assembly includes a bearing support frame configured to be coupled to a static frame, a plurality of ribs connected to the bearing support frame, and a bearing support connected to the plurality of ribs and configured to support a bearing of the one or more bearings. The bearing support assembly has a non-axisymmetric stiffness around a circumference of the bearing support assembly.

A bearing support assembly configured to support one or more bearings on a shaft, the bearing support assembly comprising:
- a bearing support frame configured to be coupled to a static frame;
- a plurality of ribs connected to the bearing support frame;
- and
- a bearing support connected to the plurality of ribs and configured to support a bearing of the one or more bearings,
- wherein the bearing support assembly has a non-axisymmetric stiffness varying around a circumference of the bearing support assembly, and wherein the non-axisymmetric stiffness is achieved by altering a material of one or more of the plurality of ribs.
A bearing support assembly configured to support one or more bearings on a shaft, the bearing support assembly comprising:
- a bearing support frame configured to be coupled to a static frame;
- a plurality of ribs connected to the bearing support frame;
- and
- a bearing support connected to the plurality of ribs and configured to support a bearing of the one or more bearings,
- wherein the bearing support assembly has a non-axisymmetric stiffness varying around a circumference of the bearing support assembly, and
- wherein the non-axisymmetric stiffness is achieved by altering an orientation of one or more of the plurality of ribs, wherein the plurality of ribs includes a plurality of fixed ribs and a plurality of movable ribs.
