JOURNAL FREE ACCESSIndoor test machines have been used for evaluating tire tread wear because of actual vehicle testing required much cost and time. The research paper was published and was described that the tread wear due to the drum was the same tread wear with the flat belt. Vehicles mainly travel on flat road surfaces. Therefore, a flat belt type machine should be used for investigating tire tread wear. Drum type machines, however, are used as economical testing machines.
In this paper, we investigated analytically the influence of drum curvature on the tire tread wear by calculating the friction energy in the contact surface. The analytical results were compared with experimental results that had published. We obtained the relationship between the friction energy on the flat belt and on the drum. Analytical results was good agreement with experimental results.View full abstractDownload PDF (662K) -

JOURNAL FREE ACCESSThe mold release properties of HNBR/zinc-methacrylate have been studied. Increasing the content of zinc-methacrylate, the adhesive strength to mold increased. Analizing the mold surface by micro-FTIR and IR-RAS, firstly, the poly- zinc-methacrylate adhered to the mold surface and subsequently, the rubber adhered to the mold.
The mold release agents on this compound were studied. The best internal release agent was Na-dodecylbenzenesulfonate and the generally-used release agents such as wax and silicone showed little effect. The particular agents were better for an external commercial mold release agent.View full abstractDownload PDF (372K) -

JOURNAL FREE ACCESSTo improve the carbon black surface, the postgrafting of polymers onto the surface by the reaction of pendant glycidyl groups of grafted polymer on the surface with functional polymers having terminal amino groups was investigated. The grafting of polymers having pendant glycidyl groups was achieved by the copolymerization of methyl methacrylate(MMA) with glycidyl methacrylate (GMA) initiated by azo groups introduced onto the surface. Poly(MMA-co-GMA) grafted onto carbon black surface was found to react with functional polymers, such as poly (ethyleneimine) (PEI), diamine-terminated poly(ethylene oxide) (PEO-NH2), and diamine-terminated poly (dimethylsiloxane)(SDA), and the corresponding polymers are postgrafted onto grafted polymer on carbon black surface: the percentage of postgrafting of PEI, PEO-NH2 and SDA was determined to be 13. 7, 27.4 and 4.5%, respectively. The percentage of postgrafting increased with increasing GMA content of grafted chains on the carbon black surface. The number of postgrafted PEI decreased with increasing molecular weight of PEI.View full abstractDownload PDF (685K) -

JOURNAL FREE ACCESSThe spring bedded ring model has been widely used for structural analyses of tire deformations under quasi-static and dynamic loading. Analyses on spring constants in the radial, the lateral and the circumferential directions, denoted by Kr, Ks and Kt respectively, have been conducted previously, however, were confined to only static cases. In this paper, by solving the equilibrated configuration of radial tire sidewall under inflation perssure and centrifugal force, we obtain finite deformations due to various loadings at the sidwall end near the tread. Then, we determined non-linear spring constants of a rotating radial tire Kr, Ks and Kt, which are compared with the experimental results given by referred papers.View full abstractDownload PDF (555K) -
