...Richard Hollenbach; Robert Kielb; Kenneth Hall This paper builds upon a two-degree-of-freedom Van der Pol oscillator-based reduced-order model for studying the mechanisms around nonsynchronous vibrations (NSV) in turbomachinery. One degree tracks the fluid motion utilizing a combination...

... the coefficients in the reduced-order model (ROM) to improve the accuracy in comparison to experimental data. Second, a cubic stiffness term is added to the fluid equation; this term is often seen in the Duffing Oscillator equation, which allows this ROM to capture the experimental behavior more accurately, seen...
