摘要：
Exploring Noise Reduction in Automotive Disc Brake Systems: Investigating the Impact of Viscoelastic Core Sandwich Plates. This study delves into the phenomenon of brake squeal noise generated by automotive disc brake systems. It focuses on analyzing the response of sandwich plates with viscoelastic cores, which are employed within brake systems to mitigate squeal noise arising from friction between brake pads and the brake disk. Through a series of finite element analyses conducted under varying operational conditions, including friction coefficient and angular velocity, the research aims to ascertain the complex eigenvalue of the disc brake system in order to identify unstable modes. The findings underscore that the incorporation of viscoelastic layers within preloaded, slender sandwich plates introduces nonlinear dynamic characteristics that contribute to the reduction of squeal noise within braking systems. © The Author(s) 2024.
