2019年1月1日 · This study presents a rational methodology to predict the tire’s failure life at the steel belt edge region due to high speed regulation test. Based on the finite element analysis and fatigue characteristic of rubber material, a method to determine exact failure time is proposed.

It is to be noted that belt edge cracks are common to steel belted radial tires due to the large stress concentration that is present at the belt edge from the material stiffness...

2015年11月1日 · However, a whole tire model needs about 50 million elements because rubber in the tire needs to be fine meshed, especially around the belt edge to obtain the strains accurately. To solve this problem, a global–local analysis was …

It is shown that belt edge strip and nylon cap ply covering belt edge at the belt peripheries were the most effective elements improving belt durability. It is also shown the nylon full cover works better than an additional steel belt layer to reduce maximum interlaminar shear strain and strain energy density at belt edge.

A three-dimensional fracture mechanics model is formulated to study fatigue crack growth and durability in tires. The application of this model in a radial medium truck tire reveals fracture...

2004年6月9日 · Tire durability, in one way or another, is frequently related to the fracture of tire components, such as belt edge separation, ply ending separation, or lug cracking in radial medium truck (RMT...

Belt Edge Separation CAUSES: Breakdown adhesion between the belts: • Under infl ation and/or overload. • Excessive speed. • Fast cornering. • Axle misalignment. • Constant deformation of the casing structure. RECOMMENDATIONS: • Use tyres at recommended pressure and do not exceed maximum load (Load Index).

2005年3月29日 · One belt edge cover is placed at the edge of each steel belt, one at the top and another on the bottom. This is an area of extremely high stress. When the belts are flattened out, they want to pantograph like a Chinese finger trap.

2001年4月1日 · The study of fatigue crack growth resistance for tire belt compounds is motivated by the high deformation cycles inherent in the belt edge region of radial tires. To improve the understanding of fatigue in this region, a test has been developed to simulate crack growth in shear (mode III).

2024年2月22日 · This research paper focuses on studying the phenomenon of belt edge separation in tires by investigating the effect of belt lay arrangement on this failure mode. The study examines two types of belt arrangements, namely Symmetric and Asymmetric, in both four belt and three belt package configurations, using advanced finite element analysis (FEA ...
