Investigating CURVIC coupling behavior by utilizing the two- and three-dimensional boundary and finite element methods S.R. Pisani*, J.J. Rencis* "General Electric Company, 1000 Western Avenue, Lynn MA 01910, USA ^Mechanical Engineering Department, Worcester Polytechnic Insitute, 100 Institute Road, Worcester MA 01609, USA ABSTRACT This work investigates the behavior of CURVIC® [1] couplings through two- and 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
