The present paper introduces a tire/road friction prediction tool based on modelling the tire/road contact as dynamic, viscoelastic, rough, and lubricated. The tool takes into account a considerable part of influent parameters related to tire, road, contaminant, and contact operating conditions:

  • For the tire, the tool takes into account its geometry and rubber material behaviour.

  • For the road, the texture is taken into account via the surface topography.

  • At the contact interface, dry or wet conditions are taken into account through the lubricant depth, viscosity, and density.

  • The operating conditions are taken into account through the normal load, speed, and slip ratio of the tire.

The real novelty of this tool lies in its ability to reproduce the complete curve of the tire/road friction coefficient as a function of the slip rate. The validation of the tool is initially done through parametric studies by analyzing the trends of the results, then by performing braking tests on a passenger car at various speeds on different wet roads with different textures. The tool correctly ranks the peak friction and the sliding friction on these various road surfaces.

轮胎/道路摩擦预测:介绍一种基于接触建模的简化数值工具

本文介绍了一种基于动态、粘弹性、粗糙和润滑的轮胎/道路接触建模的轮胎/道路摩擦预测工具。该工具考虑了相当一部分与轮胎、道路、污染物和接触操作条件相关的进水参数:

  • 对于轮胎,该工具会考虑其几何形状和橡胶材料行为。

  • 对于道路,通过表面地形考虑纹理。

  • 在接触界面,通过润滑剂深度、粘度和密度考虑干燥或潮湿条件。

  • 通过轮胎的正常负载、速度和滑移率将运行条件考虑在内。

该工具的真正新颖之处在于它能够再现作为滑移率函数的轮胎/道路摩擦系数的完整曲线。该工具的验证最初是通过分析结果趋势的参数研究完成的,然后通过在具有不同纹理的不同潮湿路面上以不同速度对乘用车进行制动测试。该工具正确排列了这些不同路面上的峰值摩擦和滑动摩擦。
