These terms are called cross-coupled stiffness, cross-coupled damping, and cross-coupled mass. When there is a positive cross-coupled stiffness, a deflection will cause a reaction force opposite the direction of deflection to react the load, and also a reaction force in the direction of positive whirl.

Aerodynamic cross-coupled stiffness is one of the main contributors to rotordynamic instability in modern turbo-machines. The destabilizing effects of the cross-coupled stiffness are demonstrated. H2 and H¥ synthesis approaches are used to design controllers that may stabilize the rotor-bearing system over a wide range of cross-coupled ...

Consider a perfectly smooth wheel and rail where the support stiffness provided by the rail, K, varies with distance x.For relatively low frequency variations the wheel can be represented simply by a mass, M w, and a static load, F 0.Writing the response of the wheel as a quasi-static deflection of the track, u 0, and a dynamic component, u, this satisfies

XLPIMPLR produces (2×2) stiffness, damping, and mass matrices for centrifugal pump impellers. The code provides a library of pump impellers based on Sulzer-pump empirical data. XLWACHEL uses Wachel’s empirical formula to calculate destabilizing cross-coupled force coefficients for impellers of centrifugal compressors.
