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

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

    Sammanfattning : 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.

  3. 2. Wheel Brake Noise Analysis

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Teodor Hamnholm Löfgren; [2017]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Viktor Wiese; [2017]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

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

    Sammanfattning : 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. LÄS MER

  7. 5. Investigation of Causes for Wheel Squeal on Roslagsbanan in Stockholm

    Master-uppsats, KTH/Spårfordon

    Författare :Zhan Ouyang; [2014]
    Nyckelord :;

    Sammanfattning : The purpose of this work is to investigate the possible causes of wheel squeal on Roslagsbanan, a narrow gauge (891mm) suburban railway system in Stockholm, Sweden. Simulation of the dynamic behaviour of vehicles negotiating curves was carried out by means of the Swedish multibody simulation software GENSYS [1]. LÄS MER
