橡胶材料松弛时间谱与滚动摩阻的关系

Relation of Relax Time Spectrum and Rolling Friction About Rubber Material

橡胶材料的微观结构是其松弛时间谱的内在因素。通过广义的Maxwell模型 ,研究其松弛时间谱与滚动摩阻的关系 ,得出了轮胎滚阻系数与松弛时间谱的计算关系并讨论了滚轮前进速度对滚动摩阻系数的影响。

The microstructure of rubber material is an intrinsic factor of the relax time spectrum. Introducing the generalized Maxwell model and corresponding the relax time spectrum lead to the calculating relation of the tire rolling coefficient and relax time spectrum, and the influence of velocity on coefficient of rolling friction is discussed.
