Abstract
The objective of this paper is to present a numerical approach for analyzing parameter excited vibrations on
a gas compressor, induced by the nonlinear characteristic of the arc spring feature of certain designs of squeeze film
dampers, SFDs. The behavior of the journal is studied in preparation for varying the damping characteristics of the
SFD as well as the dynamic forces acting on the SFD. Phase plane orbits together with Poincar´e maps are given for
different arc spring damping and static and dynamic load cases. Besides, bifurcation diagrams as a function of the arc
spring damping and forces acting on the SFD are presented. It is worth mentioning, that the maps and diagrams can be
used as design guidance. Finally, a comparison between the numerical results and experimental result is facilitated in
form of waterfall diagrams. For this, a full scale model of the arc-spring damper was designed and build.
