224 • Case 1: FX=20N, FY=15N ‐ Exhibits true 2D friction behavior ‐ Almost no stick-slip behavior (pure stick or pure slip only) ‐ Low number of harmonics needed (NH=3) • Case 2: FX=20N, FY=2N ‐ Could be modeled with 1D friction ‐ Comparison to 1D friction shows good matching ‐ Stick-slip behavior on almost the whole frequency range ‐ High number of harmonics needed (NH=15) 2023R1 Example: Simplified model of blade-disk assembly with under platform damper [Poudou thesis 2007] Case 2 Case 1 Trajectory of the friction point at F = 32.9 Hz UX @ tip of the beam
