A Reduced-Order Model for Complex Modes of Brake Squeal Model and Its Application to a Flexible Pin-on-Disc System

Figure 4

Comparison between the frequencies versus of original model with those of reduced-order model (a) in the frequency range of 0.5–4.3 kHz and (b) in the frequency range of 6.9–10 kHz. Blue points—exact frequencies; green points—frequencies of reduced-order model; red line—original perturbation frequency locus; black line—reduced-order perturbation frequency locus. Fixed parameters: , , , , , , and .
