Application of the finite-element method (FEM) to specify design model when defining rotor critical speeds by classical methods

Abstract

This work demonstrates by the example of calculation of LPC rotor critical speeds that application of FEM allows to specify greatly the design model developed by initial parameters method due to consideration of compliance of stator elements of complicated and to achieve good compliance of design and experimental data.
