Seminar - Tyre/Road Noise and Vibration: Understanding Their Interaction and Contribution to Vehicle Noise and Fuel Consumption by Prof. Ines Lopez-Arteaga

Date: 26 October 2015 (Monday)

Time: 2:30 pm – 3:30 pm

Venue: EF305, The Hong Kong Polytechnic University

Abstract:

Tyre/road noise and vibration are the main sources of road traffic noise, which is an increasingly big problem in densely populated areas. At the same time, rolling resistance, caused by the energy losses in the tyre, is a significant part of the total vehicle losses and, therefore, directly affects fuel consumption and CO2 emissions. In order to reduce both noise emissions and energy consumption a good understanding of tyre/road interaction and of the influence of tyre and road properties is needed. In this paper the main tyre and road parameters that influence tyre/road noise and rolling resistance are discussed. Special emphasis is placed on tyre/road contact, since the contact forces between tyre and road are the key to a reliable prediction of tyre/road noise, rolling resistance and wear. Although tyre/road models are widely applied to the prediction of tyre/road noise and low-noise road design, the potential of these models for low-rolling resistance road design is not yet fully exploited.

Bio-sketch:

Lopez Arteaga received her PhD degree at the University of Navarra in San Sebastian (Spain) in 1999. She is full professor in Engineering Acoustics at the Marcus Wallenberg Laboratory for Sound and Vibration Research at KTH, where she leads the Material and Structural Acoustics group and she is also affiliated as associate professor to the Mechanical Engineering Department at Eindhoven University of Technology (Netherlands). Her research field is vibro-acoustics and her main interests are tyre/road interaction, inverse acoustics and thermo-acoustics. She has supervised 16 PhD students (7 finished), published more than 80 papers in refereed journals and refereed conference proceedings and 3 patents. She is subject editor for the Journal of Sound and Vibration and member of the board of directors of the International Institute of Acoustics and Vibration (IIAV).
