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...

To produce thin grooves in the tread portion of tires, tire molds contain a multitude of sipes, which are thin metal inserts that project into the tread rubber during molding and curing. The geometric design and location of sipes is based on tire performance as well as appearance. A completèfamily' of tires, typically consisting of a dozen or more tire sizes with similar tread designs, will req...

Abstract Energy-saving tires have been developed by researchers in the industry order to minimize hysteresis loss. In general, this is achieved combining precipitated silica sourced from sand with a silane coupling agent. This strategic reaction serves elevate performance characteristics of tread tire, effectively enhancing their properties. Therefore, research aimed investigate utilization com...

The tread of a tyre consists of a profile (pattern of grooves, sipes, and blocks) mainly designed to improve wet performance and to inhibit aquaplaning by providing a conduit for water to be expelled underneath the tyre as it makes contact with the road surface. Testing different tread profile designs is time consuming, as it requires fabrication of a tyre set using the tread profile, followed ...

The subsurface defect in the wheel tread caused from Rolling Stock Fatigue (RCF) has become more danger in high speed railway. The conventional UT and phased array UT have deficiency to find the subsurface defect from the tread surface because of limitation of ultrasonic near field. In this paper, the subsurface defect is studied by simulation and experimental results with ultrasonic technique....

this research work is devoted to the investigation on the use of silica on the fatigue-to-failure property of a tire tread compound. a reference compound was frst designed in which 60 phr carbon black was used as the reinforcing fller. while keeping the total of fller content to be constant as 60 phr, three additional compounds with 5, 10 and 20 phr silica were then manufactured. the classical ...

Along with the developing technology in rubber industry, use of natural and synthetic rubbers as well liquid has increased significantly recent years. The formulation tread compound, which directly affects performance a tire, is generally produced from rubbers. Intensive scientific studies have been carried out on because they reduce consumption process oils used tire production phase increase ...
