The project SPERoN 2020 - Design of silent tyres with low rolling resistance is part of the german research project LeiStra3 (Silent road traffic 3). Based on advanced tyre/road noise simulation models created by Chalmers during the last years, the project focuses on the development of quieter tyres with lower rolling resistance. The main goal is to understand the influence of the tyre construction on noise and rolling resistance. The research at Chalmers focuses on the development and application of numerical models for tyre/road interaction. For this, state of the art contact models are combined with a precise, yet efficient, tyre model. A particular focus is laid on increasing the understanding of the physical processes associated with sound radiation and energy dissipation of rolling tyres. This will contribute to the development of more silent tyres with reduced fuel consumption which will reduce the impact of the road transportation sector on public health and the environment.
The project is carried out in cooperation with the Technische Universität Hamburg-Harburg, the Leibniz Universität Hannover and the tyre manufacturer Continental, and runs from 2011 to March 2014.
The project is carried out at the Division of Applied Acoustics in the research group Vibroacoustics, at Chalmers.
