Reduction of Squeal Noise from Disc Brake Systems Using Constrained Layer Damping
Squeal noise generation during braking is a complicated dynamic problem which automobile manufacturers have confronted for decades. Customer complaints result in significant yearly warranty costs. More importantly, customer dissatisfaction may result in rejection of certain brands of brake systems. In order to produce quality automobiles that can compete in today’s marketplace, the occurrence o...
متن کاملExperimental analysis on squeal modal instability
In this paper, an experimental analysis performed on a simplified brake apparatus is presented. Brake squeal is a major concern in braking design. During past years a common approach for squeal prediction was the complex eigenvalues analysis. Squeal phenomenon is treated like a dynamic instability. When two modes of the brake system couple at the same frequency, one of them becomes unstable lea...
متن کاملA combined approach of complex eigenvalue analysis and design of experiments (DOE) to study disc brake squeal
This paper proposes an approach to investigate the influencing factors of the brake pad on the disc brake squeal by integrating finite element simulations with statistical regression techniques. Complex eigenvalue analysis (CEA) has been widely used to predict unstable frequencies in brake systems models. The finite element model is correlated with experimental modal test. The ‘input-output’ re...
متن کاملInstability prediction of a fully updated brake system with uncertainty in contact conditions
Brake squeal, as friction-induced audible noise above 1 kHz to 20 kHz, is a major concern to automotive manufacturers because of noise, vibration and harshness performance and warranty-claim related costs. The prediction of brake squeal is as difficult as ever due to nonlinearities, uncertainty boundary and operating conditions. The exact contact conditions between pad linings with rotor are of...
متن کاملDr. ETTEMEYER Application Report No. 04-00 New Techniques and Applications for 3D-Brake Analysis
The measurement of brake squeal vibrations is a difficult problem, because the rotating disc does not allow any physical contact with the sample during measurement. The use of accelerometers is difficult and very time consuming. Non-contact scanning techniques (e.g. vibrometers) are widely used for these applications, and although they provide a very high temporal resolution is available, still...
