| 中文摘要: |
| 分析全钢载重子午线轮胎肩空脱层现象的原因并提出相应的解决措施。结果表明，轮胎半成品部件界面污染、部分部件厚度超差、胎肩垫胶移位、易生热、帘布渗胶性能差、轮胎选用不当等是造成全钢载重子午线轮胎发生肩空脱层的主要原因，通过改进配方、优化工艺控制流程等措施，肩空脱层轮胎理赔率降低74.39%。 |
| 英文摘要: |
| The causes of shoulder space delamination of all-steel truck and bus radial tire were analyzed，and corresponding solutions were proposed.The results showed that interface pollution of tire semifinished components，excessive thickness of some components，displacement of tire shoulder pads，susceptibility to heat build-up，poor rubber permeability of tire fabric，improper selection and use of tires were the main causes for shoulder space delamination of all-steel truck and bus radial tire.By optimizing the formula and the process control flow，the compensation rate of shoulder space delamination tires decreased by 74.39%. |
