Abstract: Acoustic and dynamic measuring techniques are applied to locate the area where squeal is present on a wear scar under reciprocating sliding. SEM observations and 3 Dimension topography measurements of wear scars are conducted. A comparative investigation on characteristics of scar surfaces is carried out under both silent and squealing conditions. The result shows that the area of a wear scar with squeal is characterized by uneven and serious pit-like detachment of the specimen material. Mechanism of generation of squeal is also discussed based on the detachment of the material.
