| 中文摘要: |
| 研究横向花纹沟槽角度与轮胎残余回正力矩（TPRA）的相关性。结果表明：当其他花纹块的横向花纹沟槽角度固定时，TPRA随左肩和右肩花纹块横向花纹沟槽角度的增大而增大；随左中、中间和右中花纹块横向花纹沟槽角度的增大而减小；拟合得到了横向花纹沟槽角度与TPRA的关系方程，并通过光面雕刻花纹轮胎试验验证了方程的可靠性。 |
| 英文摘要: |
| The correlation between the groove angle of transverse pattern and the tire residual aligning torque （TPRA） was studied.The results showed that when the angles of transverse pattern grooves of other blocks were fixed，TPRA increased with the increase of the left shoulder and right shoulder block transverse pattern groove angles，and decreased with the increase of the left middle，middle and right middle block transverse pattern grooves angles.The equation of the relationship between the groove angle of transverse pattern and TPRA was obtained by fitting，and the reliability of the equation was verified through the test results of smooth carved pattern tires. |
