 Obiettivo del progetto (Objective)

'The increasing complexity and shorter development times of vehicles require more accurate and efficient simulation tools. Already in the early phases of the vehicle development, a reliable prediction of the tire dynamic behavior is required to assess and optimize vehicle performances, such as, tire/road noise, handling, ride comfort, vehicle NVH (Noise, Vibration and Harshness) and durability. In addition, the tire dynamic behavior plays a key role in several new automotive technologies, such as, intelligent driver assistance systems, active suspension, in-wheel electric drive, intelligent tires,… The objective of this project is to obtain more accurate structural tire models through a better understanding of the influence of rolling on the tire dynamic behavior. Up till now, the physical phenomena that determine the complex dynamic properties of a rolling tire are not fully understood due to the strong multi-disciplinary nature of the subject. Consequently, the current tire models are not able to provide an efficient and accurate prediction of the rolling tire dynamic behavior. This project studies the physical phenomena through an integrated approach in which the state-of-the-art in the field of experimental and numerical tire dynamic analyses are linked and consolidated. Based on the obtained insights, the effects of rolling will be implemented in existing tire models in order to improve their accuracy and applicability. The developed implementations will be experimentally validated afterwards. The integrated research approach of this project is based on a continuous transfer of scientific and engineering knowledge between industry and academia. Through secondments, recruitments, training and networking activities, this knowledge will be efficiently transferred. The outcome of the project will strengthen the European automotive industry and research through the availability of efficient and accurate tire dynamics simulation tools.'

Introduzione (Teaser)

An EU team developed tools for modelling tyre performance in automotive design. The research involved industry-academia exchanges consisting of 10 secondments or recruitments.

Descrizione progetto (Article)

The modern process of designing vehicles uses simulation tools to accelerate development time. Tyres are a vital part of vehicle performance, including noise and handling, yet until recently the response of tyres was too complex to simulate.

With EU funding, the http://tiredyn.org (TIRE-DYN) project aimed to develop more accurate tyre models by describing the effects of rolling on tyre response. The project studied the physics of rolling tyres through experimental and quantitative analyses. The resulting new simulation tools were to be experimentally validated. The three-member undertaking ran over four years to August 2014.

The research relied on transfer of knowledge between academia and industry, to be achieved through secondments, recruitments, and training and networking activities. A total of 10 exchanges took place, including recruitment and/or secondment of 3 early-stage researchers and 7 experienced researchers.

TIRE-DYN consortium members developed more accurate tools for simulating the performance of tyres. The tools strengthen the European automotive industry, improving the speed and efficiency of automotive design.
