Temperature influence on tyre/road noise on poroelastic road surface based on laboratory measurements
Abstract
The temperature effect on measured tyre/road noise is very important phenomena as it may lead to significant errors in measurement results due to substantial influence of this parameter on the obtained values. It depends mainly on the particular tyre-road combination. It is different for dense and porous as well as for bituminous and cement concrete pavements. It differs also depending on tested tyre. The correction procedure for normalizing measured noise levels to a reference air temperature of 20 oC is given in the recently published ISO Technical Specification ISO/TS 13471-1:2017 – Correction for temperature when testing with the CPX method. The temperature correction coefficients defined in the Technical Specification differ to some extent depending on the main type and condition (porosity) of a road surface. They are equal for both standard reference tyres and they slightly depend linearly on speed. An extensive study dealing with temperature influence on tyre/road noise on poroelastic road surface was conducted in the laboratory of Gdansk University of Technology in Poland. The aim of this study was to define the temperature correction coefficients for this special - extremely quiet road surface and for various tyres (including two standard reference tyres). Noise measurements using the CPX method were performed at roadwheel facilities equipped with poroelastic road surface for twelve passenger car and for two truck tyres within the air temperature range from 6 to 36 ºC. The results and findings of this experiment are presented and discussed in this paper.
