| 中文摘要: |
| 分析农业轮胎钢丝圈上抽的原因，并提出相应的解决措施。从内部、外部所有因素逐一进行分析验证，确定胎体帘线伸张和胎圈压缩率不合理是造成钢丝圈上抽的根本原因。通过适当减小胎圈压缩率和胎体帘线伸张值，并合理选取胎里直径与成型机机头直径比值，解决了钢丝圈上抽问题，轮胎的充气外缘尺寸及各项性能均满足设计及企业标准要求。 |
| 英文摘要: |
| The causes for the steel ring up-pulling of agricultural tire was analyzed and its solutions were proposed.By analyzing and verifying all internal and external factors one by one，it was determined that the unreasonable stretching of the carcass cord and the compression rate of the bead were the fundamental reasons for the steel ring up-pulling.Through appropriately reducing the compression rate of the bead and the elongation value of the carcass cord，and selecting suitable ratio of the inner diameter of tire to the head diameter of building machine，the problem of steel ring up-pulling was solved，and the inflated peripheral dimenmion and various performance of the tire met the design and enterprise standard requirements. |
