Abstract
A radial element centrifugal compressor vane has been analyzed by means of the Structural Analysis and Matrix Interpretive System (SAMIS). The displacement method and finite element technique were used. Initial studies of configurations where exact solutions were readily available were conducted to ensure the applicability of the method.
The results of the stress analysis are presented along with the deflections. The first natural frequency was also determined along with the associated mode shape and these results are also presented.
