... a harmonic balance method-based approach presented in a previous paper. It accounts for unilateral contact and dry friction of the rotating blade against a rigid casing through a regularized penalty law. A Lanczos filtering technique is also employed to mitigate spurious oscillations related to the Gibbs...

... Harmonic Balance Method-based methodologies are assessed: (1) an approach relying on augmented Lagrangians and (2) a second method using a regularized penalty law combined with a Lanczos σ -approximation filter. As a reference point for this comparison, a time-domain numerical strategy relying...

...Yann Colaïtis; Alain Batailly In this study, a frequency-domain approach based on the harmonic balance method coupled to a predictor-corrector continuation algorithm is implemented for the qualitative analysis of blade-tip/casing contacts in aircraft engines. Unilateral contact and dry friction...
