Tyre wear particle emissions have gained significant attention due to their harmful effects on the environment and human health. However, studies tyre particles generated under chassis dynamometer conditions are still scarce. This study measures instantaneous number concentrations elemental species of in different light-duty vehicle test cycles. The results show that (PN) US06 cycle much higher...

The spatial profile of the load exerted by a pneumatic tyre on pultruded glass fibre-reinforced polymer (GFRP) deck varies nonlinearly with magnitude load, owing to changes in tyre-deck contact zone’s shape, size and pressure distribution. This is rare problem which nonlinearity originates not constitutive behaviour or large displacements, but load’s 3D definition. paper addresses that three pa...

There are three types of adhesion difficulties faced by the Babylon Tyre manufactured: bonding the inner liner to the fabric cord, bonding the tread to the breaker bandage, and bonding the sidewall to the bead apex. We have investigated the adhesion between layers of tyre by using maleic anhydride (MA) in an elastomer while using phenolic resin, resorcinol, or novolak in another elastomer to un...

Tyre wet skid resistance greatly affects vehicle safety, and it is dependent on the frictional behaviour at tyre–road interface; however, currently available numerical models, using finite element method, either neglect road roughness or obtain rightness expensive computed tomography scans, rendering them inefficient complex. This study aims to present an estimation method of rubber slides a ro...

Abstract The waste tyre-derived products, including whole tyres, tyre bales, shreds, chips, and crumb rubber, have begun to be used in various geotechnical applications. In particular, the use of bales construction a lightweight embankment on soft ground has potential satisfy demand for low-cost materials exhibiting such beneficial properties. This paper presents comparison between common mediu...

The aim of this research study was to analyse the approaches for establishing a spatial model radial truck tyre, based on finite element method, in order perform realistic analysis static as well dynamic tyre–pavement interactions. A complex rubber tyre having large number elements formulated combining current state-of-the-art modelling techniques and, from that model, simplified smaller derive...

this research work is devoted to the footprint analysis of a steel-belted radial tyre (185/65r14) under vertical static load using finite element method. two models have been developed in which in the first model the tread patterns were replaced by simple ribs while the second model was consisted of details of the tread blocks. linear elastic and hyper elastic (arruda-boyce) material models wer...
