Myklestad’s Method for Predicting Whirl Velocity as a Function of Rotational Velocity for Flexible Multimass Rotor Systems

Abstract

A simple numerical procedure is developed for determining the whirl velocity as a function of the rotational velocity for flexible multimass rotor systems that are difficult to handle by completely analytical procedures. The numerical procedure follows the Myklestad method, and introduces an effective mass moment of inertia for each disk to account for various ratios of whirl to shaft speed. The flexibility of supports is included.
