Summary:

Squeal noise is defined as noise at frequency upper than 400 Hz and occurs if the system has a very high amplitude mechanical vibration. All systems with sliding contact are prone to squeal: curve squeal noise of railway wheels, disc brake squeal, et cetera It is well known that squeal phenomenon depends on the local kinematics in the contact patch. A multi-scale approach is proposed to identify the mode selection mechanism. Contact surfaces waves are initiated under pressure and sliding velocity conditions leading to self-excitation. Disc brake squeal is treated with this approach
