摘要
介绍了所开发的轮胎橡胶摩擦试验台,提出了轮胎橡胶摩擦试验方法。在该试验台上进行了干水泥路面、冰面等工况下的轮胎橡胶块摩擦试验,对所得试验结果进行了分析、处理。初步掌握了路面、温度、垂直压力和滑移速度等因素对摩擦因数的影响。在此基础上把动摩擦的概念引入轮胎半经验模型,对现有模型进行了改进。提出了应用轮胎低速试验数据预测高速下轮胎特性的方法。
A newly developed tire rubber friction test machine is introduced. Friction test method of tire rubber is provided. Test data of tire rubber friction on concrete and icy road surface is obtained and analyzed. Effect of different road surface, ambient temperature, contact pressure and slip velocity on friction coefficient is apprehended. The dynamic friction is introduced to tire semi-empirical modeling and the accuracy of the model is improved. A way of forecast tire property on high rolling speed from low rolling speed tire test is illustrated.
