轮胎模具中套有限元分析

Finite element analysis for cone ring of tire mould

中套作为轮胎模具中的重要零件,在轮胎硫化过程中发挥着不可或缺的作用。运用力学知识,对中套进行了受力分析,并通过有限元分析软件对中套进行了热力耦合模拟分析,得出中套的位移变化趋势及不同材料和导向角的改变对中套的应力、位移的影响。中套材料为40Cr时的最大等效应力和U1方向上的位移均小于中套材料为45钢和Q235的最大等效应力。在中套材料为45钢不变的情况下,中套导向角越大,所受的最大等效应力与U1方向上的位移就越大。

As an important part of tire mould, the cone ring plays an indispensable role in the tire vulcanization process. Using the knowledge of mechanics, the force analysis of the cone ring was carried out. The thermal-mechanical coupling analysis of the cone ring was realized by finite element analysis software, and the displacement change trend of the cone ring and the influence of different materials and guiding angles on the stress and displacement of the cone ring were obtained. When the material of the cone ring was 40 Cr, the maximum equivalent stress and the maximum displacement in the U1 direction were less than those of 45 forged steel and Q235. When the material of the cone ring was 45 forged steel, the larger the guide angle, the greater the maximum equivalent stress and the maximum displacement in the U1 direction.
