Although disc brakes equip mass produced vehicles, drum brakes are still applied on
medium and heavy duty vehicles. However, both exhibit high level of brake noises which the …

Brake squeal in friction brakes is a typical audible noise phenomenon in vehicles leading to
high development and sometimes warranty costs for the suppliers. The friction forces …

Most brake vibration phenomena are caused by self-excitation based on friction forces
between pad and disk respectively drum. Brake vibrations are in general undesired as they …

Despite the fact that disk brakes are used on almost entire mass produced vehicle, drum
brakes are still applied on light-, medium-, and heavy-duty vehicles. However, both exhibit a …

The brake system creation is an important achievement for automotive production. However
there is a secondary response of this system, its noise emission. Brake noise researches …

Brake squeal—an audible high-frequency noise phenomenon in the range between 1 kHz
and 15 kHz resulting from self-excited vibrations—is one of the main cost drivers while …

This paper describes the dither control system used for suppressing drum brake squeal. The
dither force is generated by a piezoceramic actuator installed on the back plate of a drum …

Electromagnetic acoustic noise emission in variable speed induction motor is influenced by
the characteristics of Pulse Width Modulation (PWM) output from the inverter. In this paper …

This article presents the structural dynamic modification technique, applied to an active
suspended handle, to overcome the displacement limitation of a piezo stack actuator by …

The purpose of this study was to investigate the vibration characteristics caused by front and
back vented brake disc which were physical shape difference. According to theory of heat …
