| 中文摘要: |
| 采用室内转鼓稳态工况进行12R22.5全钢载重子午线轮胎滚动阻力测试，研究卡车空载和满载两种工况下轮胎充气压力和速度对轮胎滚动阻力的影响。结果表明：轮胎的滚动阻力系数在低负荷下随速度增大而增大，在高负荷下随速度增大而减小；在相同负荷下，轮胎的充气压力越高，滚动阻力系数越小，滚动半径越大；在低负荷下，速度对滚动半径无明显影响，在高负荷下，速度越大，滚动半径越大。 |
| 英文摘要: |
| The rolling resistance of 12R22.5 truck and bus radial tire was tested under indoor drum steady-state conditions to study the effects of inflation pressure and speed on the rolling resistance of tire under no-load and full-load conditions of truck.The results showed that the rolling resistance coefficient of the tire increased with the increase of speed under low load，and decreased with the increase of speed under high load.Under the same load，the higher the inflation pressure of the tire was，the smaller the rolling resistance coefficient was and the larger the rolling radius was.Under low load，the speed of the tire had no obvious effect on the rolling radius.Under high load，the higher the speed of the tire was，the larger the rolling radius was. |
