Summary

In the paper, using the direct method, stability of elastic rotating shafts (beams, pipes) working in different conditions is analysed. It is taken into consideration a constant axial force as well as a uniformly distributed load in the case of long shafts. The case of conservative load (e.g. dead weight) as well as nonconservative load acting tangentially to the shaft axis is considered. The case when the force is a wide-band Gaussian stochastic process is also discussed.

Übersicht

Mit der direkten Methode von Ljapunov wird die Stabilität von sich um die Längsachse drehenden elastischen Wellen (Rohre, Balken) unter verschiedenen Arbeitsbedingungen untersucht. Bei Wellen mit vertikaler Achse wird außer einer konstanten Längskraft auch eine gleichmäßig über die Länge der Welle verteilte Belastung berücksichtigt. Es wird dabei sowohl die konservative Belastung (Eigengewicht) als auch die in der Wellenachse gelegene, tangential wirkende, nichtkonservative Belastung und schließlich der Fall einer Längskraft aus einem breitbandigem Gaußschen stochastischen Prozeß betrachtet.
