Due to increased interest in comfort features, considerable effort has been spent on the modification of brake prototypes in order to suppress brake squeal. Recently, piezoelectric transducers have been investigated as an ...

In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be ...

Ultrasonic friction reduction is well known in metal-metal contacts. Due to the vibration, the stick phase in the contact phase vanishes and only sliding occurs. As long as the macroscopic relative velocity of the contact ...
