16. Road Surface and Tyre Interaction : Functional Properties affecting Road Dust Load Dynamics and Storage
Abstract : Luftburna partiklar (PM) är ett problem för människans hälsa, där flertalet samband mellan negativa hälsoeffekter finns mellan luftföroreningar finns, bland annat för respiratoriska sjukdomar, lungcancer och kardiovaskulära sjukdomar med flera. I länder där dubbdäck används, till exempel Sverige, Finland och Norge, och sandning av vägar och gator genomförs vintertid för att säkerställa god friktion kommer en betydande andel av partiklarna från vägslitage och nedkrossning av sand vilket bidrar till PM10.

17. The simulation of car and truck tyre vibrations, rolling resistance and rolling noise
Abstract : The road transportation sector places a severe burden on the environment in the form of CO2 emissions and road traffic noise. Both of these environmental prob- lems can be related to car and truck tyres. READ MORE

18. Dynamic contact stiffness and air-flow related source mechanisms in the tyre/road contact
Abstract : Two aspect of phenomena occurring in, and in the vicinity of the contact patch formed by a tyre rolling on a road are here investigated: 1. A detailed numerical time domain contact model is used to evaluate approximations of the tread response that are commonly embraced in tyre/road interaction models. 2. READ MORE

19. Model development for auralization of interior tyre noise
Abstract : Increasing competition has set pressure on the product development process to reduce development time and costs. Computer Aided Engineering (CAE) has been used to decrease development times by facilitating early predictions of product performances and qualities. READ MORE

20. On the influence of surface roughness on rolling contact forces
Abstract : Road vehicle tyres, railway wheels and ball bearings all generate rolling contact forces which are transferred within a finite area of contact between the rolling element and the substrate. Either it is visible or not for the human eye, a certain degree of roughness is always present on the contacting surfaces and it influences the generation of both vertical and lateral contactforces.
