摘　　要：对全钢载重子午线轮胎稳态温度场和温度梯度进行分析和计算,结合实际轮胎耐久性能测试结果和断面破坏形式,得出轮胎稳态温度场与耐久性能的关系。结果表明:轮胎断面破坏区域裂纹方向与该区域温度梯度模的最大值反方向高度吻合;轮胎寿命与轮胎破坏区域最高温度呈反比关系。The steady-state temperature field and temperature gradient of truck and bus radial tire were analyzed and calculated,and the relationship between the steady-state temperature field and durability of tire was obtained by combining the actual test results of tire durability and the failure form of the cross section.The results showed that the crack direction in the failure zone of the tire cross section coincided with the reverse direction of the maximum temperature.The tire life was inversely proportional to the maximum temperature in the tire failure zone.
