1. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems
Abstract : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. READ MORE

2. Perception of rolling noise
Abstract : Due to improvements on combustion-engines and electric-engines for cars, tyre noisehas become the prominent noise source at low and medium speeds. Models existthat simulate the noise produced by a rolling tyre, as do models that auralize differenttraffic situations from a basic data set. READ MORE

3. Modelling of wheel/rail interaction considering roughness and discrete irregularities
Abstract : The interaction between wheel and rail is the predominant source of noise emission from railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail noise concerns rolling noise and impact noise caused by the vertical interaction excited by roughness and discrete irregularities of the wheel/rail running surfaces, respectively.

4. Tread Braking of Railway Wheels - Noise-related Tread Roughness and Dimensioning Wheel Temperatures
Abstract : Block braking is a commonly used braking system for freight wagons and other types of railway vehicles. One or several brake blocks are pressed against the tread (running surface) of the wheel, which is also in rolling contact with the rail. READ MORE

5. Time-domain modelling of high-frequency wheel/rail interaction
Abstract : The interaction between wheel and rail is the predominant source of noise emission from railway operations in a wide range of conventional speeds. On the one hand, this wheel/rail noise concerns rolling noise and impact noise caused by the vertical interaction excited by roughness and discrete irregularities of the wheel/rail running surfaces, respectively.
