Stability characteristics of rotating systems with journal bearings on viscoelastic support

An analysis for determining the stability limit of the rotor speed of a rotor shaft system, is given. The system consists of a single rotor disc in the middle of an elastic shaft having identical plain cylindrical journal bearings at the ends, supported on viscoelastic supports. The influence of sup...

Description
Summary:An analysis for determining the stability limit of the rotor speed of a rotor shaft system, is given. The system consists of a single rotor disc in the middle of an elastic shaft having identical plain cylindrical journal bearings at the ends, supported on viscoelastic supports. The influence of support parameters on the stability limits of the rotor shaft system has been studied. Die vorliegende Arbeit hezieht sich auf die Bestimmong der Drehzahlschwelle für die Stabilität eines Rotorsystems, das aus einer in der Mitte ein Disk Trangenden Welle and zwei viskoelastisch gestützten zylinderischen Lagern hesteht. Der Einfluß van verschisdenen Stütztungsparametern auf die Stabilität wird untersucht, un die optimale Werte für eine hohe Stabilität giwinnen zu können.
