In order to extend the capabilities of the DLR FlexibleBodies library for such use cases; a new Modelica class has been implemented which is based on the analytical description of an annular Kirchhoff plate. In addition the so-called Arbitray Langrangian-Eulerian (ALE) representation has been adopted so that rotating and non-rotating external loads may be applied conventiently to rotating plates.
Besides these particularities the new class AnnularPlate completely corresponds to the concept of FlexibleBodies library with the two already available model classes Beam and ModalBody.
This paper gives an overview on the theoretical background of the new class AnnularPlate; explains the usage and presents application examples.
Keywords: Arbitrary Lagrangian-Eulerian approach; annular Kirchhoff plate; flexible multibody system
