Dynamics of Rotor/Bearing System With Flexible Rotor and Flexible Bearing Support
Volume 1D: 16th Biennial Conference on Mechanical Vibration and Noise, 1997Abstract The paper analyzes, theoretically and experimentally, the lowest four lateral modes of an isotropic rotor/fluid-lubricated bearing system with flexible rotor and flexible bearing support. The parameters of the analytical model of the system are identified using sweep-frequency modal testing of the rotor rig.

A method is presented for computing the size and angular location of the correction weights required in selected planes of rotation to balance a flexible shaft rotating at high speeds. It is based on mobility principles and requires a minimal number of measurements.

The effects of flexibility on balancing may be small for many rotors that operate well below their first critical speed. The effects, however, are always present and, when very small balancing errors are required to produce an acceptable noise level, even small effects can become important.

The Vibration and Balancing of an Unbalanced Flexible Rotor
Journal of Mechanical Engineering Science, 1959The motion of a flexible unbalanced rotating shaft is examined. The effects of balancing such a shaft (as a ‘rigid body’) in a conventional low-speed balancing machine are explained. The underlying theory of a general method of balancing flexible rotors, mode by mode, is then given.

Modelling of a flexible rotor maglev system
2006 American Control Conference, 2006This paper describes the modelling process of a mechanical system consisting of a rotary flexible spindle hovered by active magnetic bearings (AMB), whose potential uses in the machine-tool industry have been well documented. The modelling takes into account the three main behavioural characteristics of such magnetically-levitated rotor: the rigid ...

Abstract : The determination of the critical speeds of a flexible rotor is usually carried out on the assumptions of negligible bearing mass and stiff ness. In this report the effect of bearing mass and stiffness on the natural frequencies of a uniform flexible shaft is found.

A Flexible Rotor on Flexible Supports: Modeling and Experiments
Volume 15: Sound, Vibration and Design, 2009In this study, a flexible rotor with variable support stiffness has been analyzed. Simple support models consisting of mass, spring systems are extracted from modal analysis of the isolated support and by applying static loads to the finite element model of the supports.

Abstract Bearings serve to link machine parts with relative motion. Sometimes this primary role is exceeded with oil-film bearings, and the self-excited-vibration oil whip occurs. A stability criterion which includes the effect of rotor flexibility has been devised through an electric-analog study, and interpretation on the basis of ...
