摘　　要：在轮胎静垂直特性建模的基础上,探讨了利用轮胎模态参数对轮胎纯侧偏特性的建模。通过侧向激振试验提取了轮胎的侧向模态参数并计算了轮胎在不同载荷下的偏离特性,计算结果与以往轮胎的试验结果具有很好的一致性。计算结果转化为无量纲形式并与经验模型进行了比较。建模和计算结果充分说明了模型的合理性并显示了建模方法的优越性。Based on the model of tire static vertical properties, the modeling of tire pure cornering properties by using modal parameters is studied. Through lateral exciting experiment the lateral modal parameters of a tire are extracted and the cornering properties of the tire under different loading conditions are calculated. The calculation results correspond to experimental results well. The results are transformed to no-dimensional form and compared to empirical models. Modeling and calculation results fully show the advantages and reasonability of the method.
