“…either the tire or the rubbing surface against tire) stationary [4] would induce material loss from tires while also increasing the surface temperature. Both open [2] and closed [4] environments are used for tire testing. A closed-type environment where the environment can be artificially controlled is suggested for the apparatus.…”

Peripheral velocity, floor surface, contact pressure and patch area, acceleration and deceleration, camber angle, turning and contact slip, and type of rubber compounds are key determinants of tire life. However, there is no accepted method to measure tire wear against the factors mentioned above. At present, tire life is determined through field tests. Other methods include the use of a drum-type apparatus with bonded abrasive paper or abrasive particles between the tire and the drum. The limitations of these methods include the time requirement and inaccuracies in data to enable accurate analysis of tire life. As a result, the tire manufacturers find it difficult to specify the tire life with adequate degree of certainty to the customers. This gives rise to the need for a standard method to assure the life of tires for the benefit of the customers and to conduct tests to help improve tire performance. The proposed apparatus has the facility to change the operating speed, surface and the load at which the tires are tested. The overall designed length, width and height of the machine are respectively 3,000 mm, 1,150 mm and 3,350 mm. Computer-based simulation results for design evaluation suggest that the stress and strain are within allowable limits under typical loading conditions. Prototype tests proved that wear of samples are in congruence with DIN 53516. It also proved that heat buildup is present when compared with drum test results. Construction and testing of the apparatus and calibration of it are proposed as future work.

This is the second part of an article which correlates road-induced impacts on vehicle to a selection of road assessment criteria. The impacts on tyre, suspension and radiator wear are studied by running a multibody semi-trailer truck model on 270 road profiles. The model accurateness is assessed by comparing international roughness index (IRI) -impact relationships to those published in the literature. A new profile rating method uses wavelength content to predict the impacts of a specific profile on driver and passenger health and safety, truck wear and fuel consumption. It is concluded that (1) medium wavelengths severely impact fuel consumption, component wear and safety; (2) simple, two-point and four-point indices yield similar results, but the more the points the better the correlation; (3) the IRI is good at predicting general trends in road-induced vehicular impact but is weak for specific impacts and (4) tyre wear correlates linearly while component wear requires quadratic correlations.
