Abstract

A simple method of calculation of lateral critical speeds of flexible rotors with rigid supports is presents is presented. The method is mainly based on the former work of Myklestad and Prohl and considers the shaft to be divided into a number of finite elements connected by massless elastic sections. A digital computer program is then prepared to solve the finite equations resulting from the analysis. By means of this program, the critical speeds of flexible rotors can be predicted at different stiffnesses of the rigid supports and mode shape of the whirling rotor is predicted. An actual cases of a centrifugal compressor rotor having different characteristics is considered.
