摘要
研究横向花纹沟槽角度与轮胎残余回正力矩(T_(PRA))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,T_(PRA)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T_(PRA)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。
The correlation between the groove angle of transverse pattern and the tire residual aligning torque(T_(PRA))was studied.The results showed that T_(PRA) increased with the increase of the transverse pattern groove angles of the left shoulder and right shoulder blocks,and decreased with the increase of the transverse pattern groove angles of the left middle,middle and right middle blocks.The equation of the relationship between the groove angle of the transverse pattern and T_(PRA) was obtained by fitting method,and the reliability of the equation was verified through the test of the engraved patterns using smooth tires.
