| 中文摘要: |
| 对全钢载重子午线轮胎胎侧蛇形弯曲的产生原因进行分析，并提出相应解决措施。通过采取胎侧在恒温恒湿环境下停放、调整挤出机温度匹配性、合理设定混炼胶门尼粘度标准、优化耐磨胶配方及改进胎侧终口型系数等措施，有效解决了胎侧蛇形弯曲问题，降低了胎侧部件返工率，使成品轮胎胎圈类质量缺陷的理赔率由0.66%下降至0.21%。 |
| 英文摘要: |
| The causes of snake bend on the sidewall of all-steel truck and bus radial tire were analyzed，and the corresponding measures were proposed.By adopting measures such as parking the sidewall in a constant temperature and humidity environment，adjusting the temperature matching of the extrusion mschine，reasonably setting the Mooney viscosity of the compound，optimizing the wear-resistant compound formula and improving the sidewall final die openning coefficient，the problem of snake bend on the sidewall had been effectively solved，the rework rate of sidewall components was reduced，and the claim rate for quality defects in finished tire beads decreased from 0.66% to 0.21%. |
