摘　　要：为了降低轮胎高速试验的条件限制与成本,通过利用TNO不同速度下的侧偏试验数据,研究了统一轮胎模型UniTire从低速试验数据预测高速轮胎力学特性的能力。其中包括速度对动摩擦系数的影响;速度对侧偏和纵滑刚度的影响;速度对气胎拖距的影响。试验结果证明了UniTire轮胎模型在从低速轮胎试验预测高速轮胎力学特性方面具有很高的预测精度。To reduce the experimental condition restrictions and the cost of the high speed tire tests, the ability of predicting the high speed tire force and moment characteristics from the low speed tire tests was studied by means of the UniTire model using TNO lateral tire test data under different speeds, including the effects of the speed on the dynamic frictional coefficient, on the lateral and longitudinal stiffness, and on the pneumatic trail. It is proved by the test that UniTire model is characterized by high precision in predicting the high speed performances from the low speed tire tests.
