概要

In order to investigate the behaviors of parametricallyand self-excited mechanical systems, graphicallyanalytic methods in the phase plane are proposed. Unstablephenomena like parametric and self-excited vibrationshappen to appear in rotating machinery with a crack, arub, the looseness and so on. Such unfavorable vibrationsshould be detected and predicted as early as possible. Inthis paper, their characteristics are investigated and afundamental view for describing and analyzing nonlinearmodels is presented.
