Nonlinear and linearised analyses of a generic rotor on single-pad foil-air bearings using Galerkin Reduction with different applied air film conditions

Ibrahim Ghalayini et al.

Summary: This paper presents a novel application of an arbitrary-order Galerkin Reduction (GR) method for nonlinear and linearised analyses. The reliability of the method is comprehensively verified by comparing simulation results with alternative methods. The results show that the GR method is less prone to numerical divergence in transient nonlinear dynamic analysis, and it is more efficient in static equilibrium, stability, and modal analysis compared to Finite Difference (FD) method.

A comparison of modal analyses of foil-air bearing rotor systems using two alternative linearisation methods

Philip Bonello et al.

Summary: This paper verifies the accuracy of the classical linear force coefficients method (LFCM) in the free vibration analysis of foil-air bearing rotor systems and identifies cases where it gives misleading results. A novel robust procedure is proposed for the computation of the LFCM's Campbell diagrams and modal stability plots. The study also compares the LFCM's modal analysis capability with a recently developed direct linearization method, finding contradictory results to a previous study.

A computationally efficient nonlinear foil air bearing model for fully coupled, transient rotor dynamic investigations

Christoph Baum et al.

Summary: A novel physical and mathematical model of foil air bearings was developed with a focus on computational time-efficiency for rotor dynamic investigations. The model, which accounts for nonlinear deformation behavior and linear viscous damping, was validated using published experimental data and reduction technique, showing a decrease in computation time up to a factor of 1000 with a slight loss in accuracy. The bearing model was also coupled with a rigid rotor model to demonstrate its applicability during a run-up and coast-down.

A novel method for calculating the dynamic force coefficients of Gas Foil Bearings and its application in the rotordynamic analysis

Yongpeng Gu et al.

Summary: A new method for calculating the dynamic force coefficients of gas foil bearings was proposed, showing potential for accurate prediction of stability characteristics in gas foil bearing-rotor systems. The method demonstrated agreement with complex foil structure models, highlighting its accuracy and effectiveness in predicting system stability features.
