An effective way of improving the efficiency of tyre tube development is integrating, analysis and simulation into design, testing and manufacturing process. This allows designers and engineers to carry out analysis and simulation as an integrated part of tyre tube development process, and thus greatly reducing prototypes and physical testing. This paper deals with the analysis of tyre tube flu...

An 18 4R38 radial-ply tractor drive tyre was operated at 10% travel reduction, at three correctly inflated combinations of dynamic load and inflation pressures on a structured clay soil and at another combination of load and inflation pressure on a loose sandy loam and a loose clay loam soil. Soil–tyre interface pressures on the face of one lug and on an undertread region between two lugs were ...

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...

The thiols in the morning urine of 224 employees of a chemical plant were determined after alkaline hydrolysis of all urinary thioethers. The highest thioether excretion was found in rubber workers and radial tyre builders in comparison with clerks, plastic monomer mixers and footwear preparers. Smoking and medication tended to increase thioether excretion. Urinary thioether determination may p...

Tyre wear is a complex phenomenon. It depends non-linearly on numerous parameters, like tyre compound and design, vehicle type and usage, road conditions and road sUliace characteristics, environmental conditions (e.g., temperature) and many others. Yet, tyre wear has many economic and ecological implications. The possibility to predict tyre wear is therefore of major importance to tyre manufac...

Tyre behavior plays an important role in vehicle dynamics research. Knowledge of tyre properties is necessary to properly design vehicle components and advance control system. For that purpose mathematical models of the tyre are being used in vehicle simulation models. The Magic Formula Tyre Model is a semi-empirical tyre model which describes tyre behavior quite accurately. The Magic Formula T...

This paper proposes a simple mathematical tyre model that estimates tyre cornering stiffness. The model is derived by considering the tyre to be a combination of two independent systems. The sidewalls are assumed to be negligibly stiff in the lateral direction, and hence their influence on the lateral dynamics of the tyre will be ignored. The belt and tread area of the tyre will be considered t...

Future active safety systems need more accurate information about the state of vehicles. This article proposes a method to evaluate the lateral state of a vehicle based on measured tyre forces. The tyre forces of two tyres are estimated from optically measured tyre carcass deflections and transmitted wirelessly to the vehicle body. The two remaining tyres are so-called virtual tyre sensors, the...

We use new data on the location and background of entrants into the US tyre industry to analyse why the industry became so regionally concentrated around Akron, Ohio, a small city with no compelling advantages for tyre production. We analyse where the Ohio entrants originated and conduct various analyses of how proximity to other tyre firms affected the longevity of tyre producers. We also exam...

This article presents an overview on the state of the art of Tyre Pressure Monitoring System related technologies. This includes examining the latest pressure sensing methods and comparing different types of pressure transducers, particularly their power consumption and measuring range. Having the aim of this research to investigate possible means to obtain a tyre condition monitoring system (T...
