Study and Analysis of Domestic and Overseas Test Standards of Tyre Rolling Resistance and Influence Factors

摘要

Tyre rolling resistance is very important to energy conservation and vehicle emissions. The main test methods of rolling resistance and their disadvantages are elaborated in this paper. In order to prepare for the (EC) No 1222/2009 and ECE R117, comparative analysis of ECE and GB are taken. It's important for the tyre company inboard export tyre to Europe. The influence of tyre pressure, test speed, load and environment temperature for the rolling resistance are studied, and lay the foundation for accurately measuring rolling resistance.
