| 基于耐疲劳性能和粘合强度，采用正交试验的方法，对全钢子午线轮胎胎体胶粘合体系进行优化。通过建立裂纹扩展有限元模型以计算胎体胶的耐疲劳性能参数和测试粘合强度，采用极差分析方法确定了胎体胶粘合体系的硼酰化钴、六甲氧基甲基密胺（HMMM）和间苯二酚甲醛树脂（RF树脂）最佳用量。结果表明，优化胎体胶粘合体系的硼酰化钴、HMMM和RF树脂用量分别为0.3，2和1.5份，此优化粘合体系大幅提高了胎体胶的耐疲劳性能，增大了胎体胶的粘合强度，实现了胎体胶耐疲劳性能与粘合强度的协调设计。 |
| 英文摘要: |
| In order to optimize and balance the fatigue resistance of the carcass compound of all-steel radial tire and its adhesion strength with steel cords，the orthogonal test method was used to optimize the adhesive system of the carcass compound.By establishing a crack growth finite element model to calculate the fatigue resistance parameters of the carcass compound and testing its adhesion strength，the range analysis method was used to determine the best dosage of cobalt boroacylate，hexamethoxymethyl melamine（HMMM） and resorcinol formaldehyde resin（RF resin）.The results showed that the dosage of cobalt boroacylate，HMMM and RF resin in the optimized adhesive system was 0.3，2 and 1.5 phr，respectively.This optimized adhesive system greatly improved the fatigue resistance of the carcass compound，increased the adhesion strength and realized the balance design of fatigue resistance and adhesion strength. |
