| 摘 要： | 该文利用轮胎模态参数建立了垂直特性和侧偏特性模型,并在垂直特性模型中计入胎侧非线性柔度,使模型预测精度得到提高。分析了不同精度的垂直特性模型对侧偏模型计算结果的影响,并与试验结果进行比较。结果表明:小载荷时胎侧非线性柔度对垂直特性和侧偏特性结果影响很小;大载荷时,胎侧非线性柔度对侧偏特性预测有较大影响,侧偏刚度预测的最大误差由-18.7%降至-11.4%。侧偏模型的预测完全符合M ag ic Form u la的描述。

| Abstract: | A tire vertical sidewall model in a cornering model was built using tire modal parameters with nonlinear sidewall compliance to increase the prediction accuracy. Simulations of the cornering properties for different vertical model prediction accuracies show that for small loads,the nonlinear sidewall compliance has little effect on the vertical properties and cornering characteristics,but for large loads,the nonlinear sidewall compliance greatly affects the cornering property predictions with the maximum cornering stiffness error decreasing from -18.7% to -11.4% compared to test results.The cornering model prediction results agree with the Magic Formula predictions. |
