This paper deals with the level of detail that is necessary for representation of tread pattern in finite element tire models. Different methods for creation of tire tread mesh are systematized by two different criteria: the most common approaches and the finite element analysis type. Some of the representative approaches found in literature are given in more detail and their advantages and dis...

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...

Tread design has evolved over the years to achieve the common tread pattern used in current vehicles. However, to meet safety and comfort requirements, tread design considers more than one design factor. Tread design must consider the grip and drainage, and the manner in which to reduce rolling noise, which is one of the main factors considered by manufacturers. The main objective of this study...

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 ...

Safety of the wheels for high-speed train was investigated when the tread cleaner, which play a role in the increase of adhesion and the removal of dirt, is failed and stuck in wheel tread. The present study was performed on the basis of analyses of a combination of mechanical and thermal load due to the failure of tread cleaner during severe conditions. The finite element method was used to an...

A finite element modeling of tire using Ansys is used to analyze the free vibration of radial pneumatic tires. The natural frequencies and mode shapes of pneumatic tires are investigated. The effects of some parameters such inflation pressure, tread pattern, ply-angles and thickness of belts on the natural frequency of tires are investigated. Keywords— natural frequency, inflation pressure, tre...

Abstract In hard court tennis, players change direction by either stepping or sliding. The shoe–surface friction during these movements is crucial to player performance. Too little when may result in a slip. much attempting slide could cause the move only short distance, fail slide. To understand influence of tread design on experiments were performed individual shoe elements that replicated tr...

In the paper, analyzing the tread flange structure characteristics ,its injection mold is designed and the maneuvering tread demolding way is applied to get out flang tread .When designing demolding parts, hydraulic pressure motor and chain-gear mechanism are used. Besides, parting plane and the forming parts can be gained automatically in Pro/E(Pro/Engineer Wildfire3.0)and standard moldbase ca...

Rolling resistance is the of a wheel that will roll or rotate due to friction between outer surface and track surface. This study aims determine effect tread patterns on coefficient rolling resistance. The tires be used in this are hard compounds with ratio pattern raised by 2 mm tire hardness 79.5 Ha, using pressure variations at 30 Psi, 40 50 Psi. Coefficient value 1.39% 8.05 N. These results...
