FEA of In-Plane Shear Stresses of a Preloaded Sandwich Plate with a Viscoelastic Core: Application to the Disk Brake System

摘要

In this work a study of the response of sandwich plates with a viscoelastic core used in brake systems to attenuate squealing noise due to friction between the disk and the pads. A finite element analysis is conducted to determine the inplane shear stress distribution in the sandwich plate under various operating conditions. The effects of braking pressure, coefficient of friction between the disk and brake pads and angular speed of the disk on the in-plane shear stress are analyzed and compared. Results show that the coefficient of friction and braking pressure are the most influential compared to angular speed.
