RISStability Analysis of an Industrial Blade Accounting for a Blade-Tip/Casing Nonlinear Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the local stability analysis of periodic solutions corresponding to the nonlinear vibration response of an industrial compressor blade, NASA rotor 37, on which are applied different types of ...
Application of Numerical Bifurcation Tracking Strategy to Blade-Tip/Casing Interactions in Aircraft Engines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Building on the regularized-Lanczos harmonic balance method (RL-HBM), a previously developed frequency method, this paper presents a numerical bifurcation tracking strategy dedicated to high-dimensional nonlinear mechanical ...
Development of a Harmonic Balance Method-Based Numerical Strategy for Blade-Tip/Casing Interactions: Application to NASA Rotor 37
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: 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 ...
Assessment of Two Harmonic Balance MethodBased Numerical Strategies for BladeTip/Casing Interactions: Application to NASA Rotor 67
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study presented in this paper focuses on the analysis of rubbing interactions—including unilateral contact and dry friction—between a rotating fan blade and a rigid casing by frequency domain methods. Two previously ...
