A scenario of an automotive accident caused by tire failure is given followed by a human factors analysis of the information available to consumers on tire aging. Consumers have not been told that the age of the tire is a safety concern. It is not easy to decode the date of manufacture on tires. More publicity and prominent warnings are needed to communicate the dangers of older tires. Also, be...

The world is exposed to serious environmental problems as a result of the rapid development modern technology, which increasing rate tire consumption, difficulty its biological decomposition and accumulation that causes fires emission toxic gases harmful nature living organisms, tires act basin collect water, forms hotbeds for growth bacteria parasites. Therefore, study focused on finding solut...

The performance of agricultural tires varies with the characteristics both terrain and tractors on which they are mounted, differently affect rolling resistance, traction capacity, slip. To reduce variability test conditions, CREA developed an original mobile (MTB) bench consists a dynamometric single axle trailer pulled by tractor can be used in tests (driving wheels) resistance (driven wheels...

This article studies the influence of speed a car with low and ultra-low profile tires, 14ʹʹ 16ʹʹ, negotiating turn through an interactive software system developed by us in MATLAB environment. The changes normal lateral loads wheels are obtained characteristics side slip angle (known as slip) pneumatic tires determined. Taking into account wheels, determines center turn. for both types given. ...

BACKGROUND:The impact of tires on a deformable ground surface determines not only the ability vehicle to move, but also pressure through contact patch geometric characteristics. The soil is normalized and limited by conditions for preservation its agrophysical properties. Therefore, when creating vehicles various purposes their movement or trailers surfaces, it required calculate in design proc...

Electronic speckle pattern interferometry (ESPI) was used for the evaluation of mechanical properties of automobile tires. The tire on wheel disc was fixed on the holder and its vibration was generated by loudspeaker. Vibrational field of the whole tire was visualized by ESPI and recorded into PC. Natural frequencies of various vibrational modes were measured and results were compared with thos...

The natural frequencies and mode shapes of pneumatic tires are predicted using a geometrically accurate, three-dimensional finite element modeling. Tire rubber materials and cord layers are represented independently using “shell element” available in COSMOS. The effects of some physical parameters such as the inflation pressure tread pattern, thickness of belts and ply angles to the natural ...

This study aimed to determine the effect of supplied pyrolysis oils (oils obtained from used tyres and depolymerisation plastics) on activity hydrodesulphurisation catalyst. Each oil was added at 20% weight a standard feedstock processed pilot plant reactors under set conditions commercial unit, including an activated Following catalyst stabilisation, material changed mixture with oils. The rea...
