进行了充气压力对充气工况载重斜交轮胎影响的有限元分析。结果表明,充气工况下,充气压力对斜交轮胎外形轮廓尺寸影响明显,其外直径、断面宽度均随充气压力的增大而增加;充气压力的大小对胎圈接触应力分布影响很小,但胎圈最大接触应力随充气压力的增加而增大。 The finite element analysis of the effect of inflation pressure on the bias tire with pneumatic conditions was carried out. The results show that under inflated conditions, the inflation pressure has an obvious effect on the profile dimensions of bias tire, and its outer diameter and cross-sectional width increase with the increase of inflation pressure. The inflation pressure has little effect on the contact stress distribution of bead, However, the maximum contact stress of the bead increases with the inflation pressure.
