轮胎滚动速度效应对轮胎侧偏动特性的影响

在利用试验模态参数建立轮胎侧偏非稳态模型基础上，本文重点分析了轮胎滚动速度效应对侧偏动特性的影响。解析模型计算结构的变化趋势和文献的试验研究结果一致。表明计入轮胎滚动所带来的速度对侧偏动特性的影响是不可忽略的，它会对不同速度下行驶汽车的操稳性及横向振动产生影响。滚动速度效应对轮胎侧偏特性影响的成功建械表明了利用模态参数对轮胎建模的优越性。

The Effect of Tire Rolling Velocity on Tire Dynamic Cornering Properties

Based on the tire non steady state cornering model using experimental modal parameters, the effect of tire rolling velocity is considered and studied in the paper. The calculated results have the same trend as the experimental results in some literatures. The compared results show that the effect of introduced speed by considering tire rolling on the dynamic cornering properties can not be ignored, which can influence the vehicle steering behavior and lateral vibration under different velocities. The modeling and calculation show the advantage of modeling using experimental modal parameters.
