橡胶轮胎摩擦理论与数值化发展前景

Theory of rubber and tire friction on development of valuation

轮胎摩擦是关系汽车安全行驶的重要力学行为,汽车的操纵稳定性主要来自轮胎—路面间的摩擦力,对轮胎的研究具有重要的意义。大量的研究表明,轮胎的摩擦系数不仅与摩擦表面材料性能有关,而且与载荷、表面形态、相对滑动速度、环境因素有关,所有这些影响因素都不是线性的关系。从不同的角度详细地阐述了轮胎的研究进展情况,并通过对相关研究成果的分析,指出了下一步研究方向。

The friction of tire is important behavior on the safety of vehicle driving.Many investigations are connecting not only to the properties of contact materials,but also to the load,surface pattern,relative velocity.Several typical formulas which describe the friction from various angles are offerred.As viscoelastic property is the main part which produce the friction force,this factor is the key of the problem.
