Abstract

The paper describes the tools design process for manufacturing the bump foil of a radial gas foil bearing. The paper proposes an alternative technology for manufacturing the bump foil and a solution to the issues related to this technology, accounting for the compensating effects of residual elastic deformations after the manufacturing process. The significance of the finite element method implementation for residual deformations and stresses accounting is emphasized, aiming to minimize the negative impact of residual elastic deformation on the bearing operational parameters.
