轮胎胎面特性对侧偏模型预测精度影响分析

胎面花纹是影响轮胎性能的重要因素。文中以模态参数模型的稳态侧偏模型为基础，从理论推导和实际计算两方面说明胎而花纹刚度的重要性，其对侧偏模型计算结果的影响要大大高于对垂直模型的影响。因此，在确定轮胎解析模型中胎面花纹参数时应首先考虑其对侧偏模型的影响。

An Analysis on the Effect of Tire Tread Characteristics on the Prediction Accuracy of Cornering Model

Tread pattern is an important influencing factor on tire performance. In this paper, based on the steady cornering model using tire modal parameters directly, a finding is illustrated by both theoretical derivation and computation that the effect of tread stiffness on the prediction accuracy of steady cornering model is larger than that for vertical model. So it is pointed out that in defining tread parameters in analytic tire model, the effect of tread on steady cornering model should be considered in the first place.
