Tackling brake noise

Using laser technology to tackle the noise pollution caused by squealing breaks.

The squeal of brakes is not just irritating and annoying, it damages cars and railway wheels and the squeal is a serious environmental concern, contributing significantly to inner city noise pollution. EUREKA project E! 2122 BRAKENOISE is tackling the friction-induced vibration that can cause such excessive undesirable noise. The project partners - Bosch, LMS and Vrije Universiteit Brussel - used laser beam technology to measure vibrations and, through analysis, gained a deeper understanding of the brake noise problem. Theydiscovered that the complete brake assembly must be taken into account. LMS is commercialising the resulting measurement and analysis methods as software tools and through engineering services.
