Abstract.
This article deals with the development of an elastically foldable, bistable diaphragm geometry, which allows an increase of the compression volume of diaphragm compressors compared to the use of flat diaphragms. Using a Finite Element Model (FEM) in ABAQUS/Standard, a number of membrane geometries (truncated cone, hemisphere, cone and dome) were calculated and analyzed with regard to elastic deformation. Selected geometries were produced by Single Point Incremental Forming (SPIF) and tested by applying full-area pneumatic pressure to determine the diaphragm lifetime.
