Project: Understanding Road Generated Exterior Noise from Tyres (URGENT)

Reference: CSU 28/4/63

Last update: 27/01/2010 10:21:45

Objectives

To provide a better understanding of the mechanisms governing tyre/road noise generation.

Description

An acoustic wave propagation modal describing the influence of the overall tyre/road geometry on the generation and propagation of acoustic waves and a mechanical modal of tyre vibration in and around the contact patch will be combined to give a noise prediction facility identifying the effects of speed and tyre/road surface characteristics. This model will be validated against experimental data from both rolling road rigs and real road surface conditions.
