全钢子午线轮胎胎肩边沟设计对偏磨影响的有限元分析

Finite Element Analysis on Influence of Shoulder Groove Design on Eccentric Wear of All-steel Radial Tire

以295/75R22.5全钢子午线轮胎为例,基于有限元分析方法,研究胎肩不同边沟设计对胎肩接地压力、接地印痕及轮胎偏磨的影响。结果表明:在胎肩添加边沟可以显著降低胎肩最大接地压力;肩部偏下部位的边沟设计显著优于其他边沟设计,能够更有效地减轻轮胎偏磨。

The influence of different shoulder groove design on shoulder contact pressure,footprint and tire eccentric wear was studied by using the finite element analysis method and taking the 295/75 R22.5 all-steel radial tire as an example.The results showed that by adding side groove to shoulder,the maximum contact pressure of shoulder was significantly reduced,and the additional side groove designed at the lower part of shoulder was much better and could effectively reduce the eccentric wear of the tire.
