计及胎面花纹的子午线轮胎接地性能有限元分析

采用Abaqus软件建立带有部分胎面花纹的三维轮胎有限元模型,模拟研究不同工况下子午线轮胎的接地性能.研究结果表明：轮胎在静负荷和自由滚动工况下应力分布相似,沿轮胎中分面基本对称,最大应力在胎肩部位;在驱动工况下,高应力区向轮胎前进的反方向扩展,制动工况与此相反;在斜坡路面的应力分布与自由滚动时相似,但最大应力有所提高;侧偏滚动工况下的应力主要分布在轮胎的中分面及与侧偏方向相同的一侧,应力值明显提高.

Finite Element Analysis on Contact Performance of Radial Tire with Tread Pattern

A three dimensional tire finite element model with tread patterns was established by using Abaqus software, and the contact performance of tire under different conditions were studied. The results showed that, the stress distribution of tire under static loading and free rolling conditions were similar, which was symmetric along the central line of the tire tread, and the maximum stress located in the shoulder of tire. On the driving condition, the high stress area extended towards the opposite direction of movement, while it extended towards the same direction of movement under the braking condition. The stress distribution of tire on a slope was similar with free rolling;however the maximum stress was higher. Under lateral rolling,the stress was mainly located in the central part of the tire tread and the side along the lateral direction,and the stress level increased significantly.
