| 中文摘要: |
| 介绍全钢载重子午线轮胎胎圈耐久性能的4种试验方法，并采用其中1种进行轮胎室内耐久性能对比和分析，发现耐久设备机箱和轮胎内部温度较高是轮胎累计行驶时间异常的主要原因。采用改进措施后，轮胎的胎圈耐久性能满足企业标准要求，试验数据的精准性、稳定性和一致性较好。 |
| 英文摘要: |
| Four testing methods for the bead durability of all-steel truck and bus radial tire were introduced，and the indoor durabilities of tires were compared and analyzed by using one method of them.It was found that the high temperatures in the durability equipment chassises and the tires were the main reasons for the abnormal cumulative driving time of the tires.After implementing improvement measures，the bead durabilities of the tires met the requirements of the enterprise standards，and the accuracy，stability and consistency of the test data were good. |
