摘　　要：采用数值模拟的方法,研究了不同胎面花纹的轮胎在不同行驶速度下的表面对流换热规律,并得到相应的特征方程式。通过研究发现:轮胎胎面、侧面的平均对流换热系数均随车速的加快而增大;花纹角度对轮胎胎面平均对流换热系数影响不明显,但对胎面局部对流换热系数有一定影响;同一速度下,轮胎侧面平均对流换热系数随花纹角度的增大而逐渐减小。Based on the numerical simulation method, the surface convective heat transfer of tires with different tread patterns at different running speeds was studied, and the corresponding proper equation was obtained. It is found via examinations that the average convective heat transfer coefficient of tire tread and tire side will increase with the acceleration of vehicle speed; The effect of pattern angle on the average convective heat transfer coefficient of tire tread is not obvious, but it has some influence on the convective heat transfer coefficient at partial tire tread; At the same speed, the average convective heat transfer coefficient of the tire side gradually will decrease with the increase of the pattern angle.
