Friction Induced Vibration

Automobile brake squeal noise, which is nonlinear, friction-induced vibration in the frequency range 1–16 kHz, still remains a major problem for the automotive industry. This article presents analytical and experimental investigations into the application of dither control for active suppression of automobile disc brake squeal. Dither is a concept of active control that introduces high-frequency actuation into a system to suppress a much lower frequency disturbance. In this study, a specially designed brake system is built, in which a piezoelectric stack actuator in the piston of a floating caliper brake applies the dither input. In the experiments, squeal noise generated under the drag mode and various dynamic modes are considered. The results indicate that this piezoelectric-based dither control could effectively suppress the brake squeal noise by 5–10 dB and the squeal occurrence by up to 60% under various braking conditions.

This work is focused on identification of material properties of piezoelectric patch transducers used e.g. for structural health monitoring before attaching to the substrate structure. Two experimental methods were concerned. At first two piezoelectric patches were supplied with a pair of collocated strain gauge rosettes. Both transducers were actuated with the same periodical signal. Significant difference in the results for two transducers was found, however it was claimed to be within tolerance by the producer. As an alternative method a measurement in an optical microscope was chosen. The patch was clamped at one side and actuated by a voltage signal. The displacement of the free end was captured by the microscope and processed in a graphical editor. Finally, a finite element model of the transducer was created and its material data were obtained by calibration with experimental data.
