Abstract

Tyre is the contact part between the vehicle and road which provides various requirements of performance. Tyres are designed to absorb road irregularities, support vehicle load and provide braking/steering characteristics. An experimental test rig for single tyre test has been designed and constructed to evaluate the tyre performance characteristics under different operating conditions. The tyre load deflection characteristic has been examined by loading and unloading the tested tyre while resting on a hard surface at three inflation pressures. The results showed that the higher hysteresis losses were at tyre inflation pressure 20 psi. Three different percentages of CuO nanoparticles have been used to evaluate their effect on the tyre hysteresis losses. Transmission electron microscopy (TEM) has been performed for the analysis of nanoparticles size. Adding CuO nanoparticle in very small amounts with the enclosed air of the tested tyre can be useful for improving its performance significantly and decreasing the hysteresis losses. This has the potential for making use of the benefits of lower inflation pressure.
