The research objective of this I/UCRC Fundamental Research Program project is to develop a mathematical model of the tire-road contact characteristics. The specific goals of the project are (1) develop and implement a theory to describe the contact mechanical processes and the resulting friction properties; (2) expand upon the existing physically motivated rubber friction theories; (3) develop multi-scale representation of the rough surface in terms of a self-affine fractal description; and (4) conduct experimental testing and validation of the proposed model in the laboratory and on the track.Tires are a critical component in the overall automotive system, enabling safety and fuel economy. The research itself will have impact on the new tire compound development research. The model and the test bed will simplify a host of experiments and make possible many others that are otherwise prohibitively complex. The work is supported by the Industry Advisory Board as well as individual industry members of the center and has the potential to extend the center?s portfolio while potentially attracting new members. The results of the research will become part of the material in the ongoing Tire Mechanics course and other courses in Mechanical Engineering. The activities will dovetail with the Virginia Tech Center for Engineering Education and Diversity (CEED) to engage women and minorities to continue toward advanced degrees

本项目的研究目标是建立轮胎-路面接触特性的数学模型。该项目的具体目标是：（1）发展和实现一种理论来描述接触力学过程和由此产生的摩擦特性;（2）扩展现有的物理驱动的橡胶摩擦理论;（3）发展粗糙表面的多尺度表示，根据自仿射分形描述;以及（4）在实验室和赛道上对所提出的模型进行实验测试和验证。轮胎是整个汽车系统中的关键部件，可以实现安全性和燃油经济性。本研究本身将对新型轮胎胶料的开发研究产生影响。该模型和试验台将简化许多实验，并使许多其他复杂得令人望而却步的实验成为可能。这项工作得到了行业咨询委员会以及该中心个别行业成员的支持，并有可能扩大该中心？的投资组合，同时有可能吸引新成员。研究结果将成为正在进行的轮胎力学课程和机械工程其他课程的材料的一部分。这些活动将与弗吉尼亚理工大学工程教育和多样性中心（CEED）相吻合，以吸引妇女和少数民族继续攻读高级学位
