Application Note: Quiet Please! ... Eliminate Brake Squeal With Numerical And Experimental Vibration Analysis

Computer-aided simulation of brake noise has made impressive advances in the past few years. Likewise, 3D scanning vibrometry has substantially extended the possibilities of experimental vibration analysis. Scanning Vibrometry enables the measurement of both in-plane and out-of-plane operational deflection shapes of the relevant components in the same test setup. At Continental Automotive Systems the measurement of brake systems with scanning vibrometry including PSV-400-3D systems is fully integrated in the design optimization process to specifically avoid brake noises.
