LINEARIZED PH STABILITY THEORY FOR FINITE LENGTH, SELF-ACTING, GAS-LUBRICATED, PLAIN JOURNAL BEARINGS,

Abstract

Use of Ausman's linearized PH method to determine the threshold of half frequency whirl for a rigid rotor in self-acting cylindrical journal bearings is extended to include finite length effects. Rotating polar coordinates are used to derive the governing equation. Results obtained are generally consistent with several previous works in wide ranges of all parameters. This method is judged to give conservative results and is suitable for studying dynamic problems of more complicated systems. (Author)
