Abstract
This work investigates the behavior of CURVIC® [1] couplings through twoand three-dimensional boundary and finite element models. The CURVICs are used to couple multiple rotors in an aircraft engine compressor, and are subjected to rotational loading. The models generated include a geometrically complex three-dimensional linear elastic body with curved surfaces, and are analyzed with the BEASY® [2] boundary element and ANSYS® [3] finite element software packages. The following comparisons are made between BEASY and ANSYS: Three-dimensional modelling capabilities, the effort required to generate the models, the accuracy of results and the ability to adequately post-process the results into meaningful data.
