  1. 1. Modeling and Simulation of Brake Squeal in Disc Brake Assembly

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jenny Nilman; [2018]
    Keywords : Brake Squeal; Complex Eigenvalue Analysis; Model Validation; Parametric Study; High Frequency; Brake Noise;

    Abstract : Brake squeal is an old and well-known problem in the vehicle industry and is a frequent source for customer complain. Although, brake squeal is not usually affecting the performance of the brakes, it is still important to address the problem and to predict the brakes tendency to squeal on an early stage in the design process.

  2. 2. Wheel Brake Noise Analysis

    University essay from Linköpings universitet/Reglerteknik

    Author : Teodor Hamnholm Löfgren; [2017]
    Keywords : ;

    Abstract : The scope of this thesis is to investigate methods of recording, processing and analysing sound data from wheel brake testing in dynamometers with focus on detecting and measuring squeal. The desired outcome is a method that Scania can use to record and analyse brake sound. READ MORE

  3. 3. Brake noise : A study in multi-tonal brake squeal

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Viktor Wiese; [2017]
    Keywords : ;

    Abstract : Brake squeal is a major problem for the vehicle industry due to recla-mations and quality perception of vehicles, as well as the unpredictability of its occurrence. This report investigates the physical reasons behind a multi-tonal brake squeal generated in a motorcycle disc brake. READ MORE

  4. 4. NUMERICAL SIMULATIONS OF FRICTION-INDUCED NOISE OF AUTOMOTIVE WIPER SYSTEMS

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Océane Roure; [2015]
    Keywords : Squeal noise; wiper system; numerical simulations; finite element model; mode-coupling; design of experiments; Farmer diagram;

    Abstract : Automotive parts may be the cause of very annoying friction-induced noise and the source of many customer complaints. Indeed, when a wiper operates on a windshield, vibratory phenomena may appear due to flutter instabilities and may generate squeal noise. READ MORE

  5. 5. Analyzing an Equivalent Single Layer Shim Model to be used for Brake Squeal Reduction

    University essay from Linnéuniversitetet/Institutionen för teknik, TEK; Linnéuniversitetet/Institutionen för teknik, TEK

    Author : Hulya Özdemir; Azad Abbas; [2011]
    Keywords : Multilayer shim; equivalent single layer ESL ; Finite element analysis; Abaqus Cae; Squeal Noise; Complex;

    Abstract : The goal in this thesis was to reduce a multilayer shim model, which was modeled from steel and polymer (isotropic materials), into an equivalent single layer shim model. The procedure was to use mathematical formulations to convert a multilayer shim into an ESL (equivalent single layer) shim. READ MORE
