Abstract We study the friction when a rectangular tire tread rubber block is sliding on an ice surface at different temperatures ranging from −38 to −2 °C, and speeds 3 µm/s 1 cm/s. At low we propose that important contribution force due slip between fragments attached surface. above −10 °C or for high enough speeds, thin premelted water film occurs shearing area of real contact small. In this ...
An analysis of the water flow generated by a tire rolling over film has been carried out on an experimental level. The present investigation is focused commercial with winter V-shaped complex sculpture. Flow measurements were performed using optical technique derived from standard 2D-PIV, so-called r(refracted)-PIV. Some specific image processing tools have developed in order to take into accou...
coeffcient of friction (cof) for rubber parts is one of the key parameters in their interaction with solid rough surfaces (micrometer to millimeter scales), such as tire-road interactions. cof of rubber depends on viscoelastic properties of rubber, roughness characteristics of the counter-part surface, and process variables such as contact nominal pressure and sliding speed. due ...
This paper provides a case study of the effect of labor relations on product quality. We consider whether a long, contentious strike and the hiring of replacement workers at Bridgestone/Firestone’s Decatur plant in the mid-1990s contributed to the production of defective tires. Using several independent data sources, and looking before and after the strike and across plants, we find that labor ...
the blending of nr and br rubber blend with n330 carbon black is studied on curing behavior and the physico-mechanical properties of a sbr rubber based tire tread compound containing n234 carbon black. the effect of sulphur and accelerator contents on different properties of rubber compound is also tested with a wide range of curing agents. partial substitution of sbr with nr shows significant ...
