Barrett, “The influence of tilting pad bearing characteristics on the stability of high speed rotor-bearing systems,” in Proceedings of the Design Engineering Conference, Topics in Fluid Film Bearing and Rotor Bearing System Design and Optimization, pp. 55–78, April View at: Google ScholarCited by: In some combinations of design and condition parameters of the rotor bearing system, the dimension of rotor and rings motion trajectory can essentially increase, though it is still limited []. To decrease journal and ring oscillation amplitudes and loadings affecting the bearing, the design with three lubricant films can be used.

    The response of the rotor bearing system to known amounts of residual unbalance with a known distribution is conducted to establish the sensitivity of the rotor system design to unbalance. This technique is normally used to establish residual unbalance requirements for manufacturing of . •Rotors on hydrodynamic bearings show self-induced vibrations due to fluid-structure interaction •The response of the non-linear rotor-bearing system can be analyzed using run-up simulations over the full operating range, and shows many interesting/dangerous non-linear vibration phenomena.

In rotor design, the emphasis is on dynamics such as the positions of critical speeds, rotor response due to excitations, and rotor stability. In bearing design, the emphasis is on the lubrication, such as minimum film thickness, power loss, temperature rise, peak film pressure, and flow by: 5.

The bearing system often is contained in the same housing (integral) as the seal system. The rotor assembly is supported in the case on both ends by journal or radial bearings.

Design parameters of fluid film bearings affect the stability of rotor-bearing systems, which can be characterized using so called threshold speed and a threshold curve (depending on a shaft speed. Introduction to Dynamics of Rotor-bearing Systems includes numerous examples, from a single-degree-of-freedom system to complicated industrial rotating machinery, which serve to illustrate fundamental dynamic behaviors.

The concepts in the text are reinforced by parametric studies and numerous illustrative examples and figures. Practical Rotordynamics and Fluid Film Bearing Design book.

It is an introduction to BEARINGS, the vital tribological elements of rotating machinery that. the design of a rotor bearing system are illustrated.

The analysis starts by analyzing the uncoupled rotor structure. This is followed by an analysis of the uncoupled bearing. After the rotor and bearing properties have been illustrated, the interaction between the rotor and the bearing dynamics is investigated in a coupled analysis.
