Brake squeal control with shunted piezoceramics - efficient modelling and experiments

摘要

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 innovative way of controlling the vibrations of a brake. This paper presents an efficient mechanical model for the description of a brake with embedded transducers. Different control strategies are discussed and compared. Measurements on a brake test rig validate the obtained results. [PUBLICATION ABSTRACT]
