| 中文摘要: |
| 研究胎圈着合宽度对145R12LT 80/78N轻型载重子午线轮胎性能的影响。有限元分析表明，增大胎圈着合宽度，轮胎胎肩所受应力略大，胎圈部位所受应力减小。成品性能试验结果表明，增大胎圈着合宽度，轮胎胎圈耐久性能明显提高，胎圈间距更大，有效地解决了胎圈在存储和安装过程中的并胎圈问题。 |
| 英文摘要: |
| The effects of bead width at rim seat on the properties of 145R12LT 80/78N light truck and bus radial tire were studied.The finite element analysis showed that the stress on the shoulder of the tire was slightly greater and the stress on the bead was smaller with the increase of bead width at rim seat.The test results of the finished product showed that the bead durability of the tire was significantly improved with the increase of bead width at rim seat，and the bead spacing was larger，which effectively solved the bead merging problem in the process of bead storage and installation. |
