湿滑路面轮胎接地力学特性模型

Tire grounding mechanical model on wet roads

为研究部分滑水状态下轮胎的接地力学特性,以205/55 R16乘用车轮胎为研究对象,建立了耦合欧拉-拉格朗日滑水仿真模型。利用正交试验设计方法创建试验方案,通过极差分析、偏相关分析和多元线性回归分析,建立了适用于不同工况的湿滑路面轮胎侧偏纵滑“亚利桑那大学轮胎模型”。对比分析表明,该模型能够准确预测湿滑路面上的轮胎接地力学特性,可为研究轮胎多工况滑水性能提供理论参考。

In order to study the grounding mechanical characteristics of tire under partial hydroplaning state,the coupling Euler-Lagrange hydroplaning simulation model was established with 205/55 R16 passenger car tires as the research object,and the orthogonal experimental design method was used to create the experimental scheme.With range analysis,partial correlation analysis and multiple linear regression analysis,the"University of Arizona Tire Model"was established for different working conditions of wet road tire sideways longitudinal slip.Comparative analysis shows that the model can accurately predict the grounding mechanical properties of tires on wet slippery road,which provides a theoretical reference for the study of the hydroplaning performance of tires under multiple working conditions.
