基于一种新开发的轮胎胎面橡胶摩擦试验机,建立了轮胎和整车与冰面间的模拟摩擦试验手段,提出了在高滑移速度段的瞬时试验法和低滑移速度段的连续采样试验法;分别在不同滑移速度、压力、温度下针对轮胎胎面胶块与冰面进行了摩擦试验,并对试验结果进行了模型拟合和分析.结果表明:作为轮胎主要组成部分的橡胶表现出很特殊的摩擦特性,其并不符合库仑摩擦定律;橡胶轮胎的机械特性在很大程度上取决于橡胶的摩擦特性,在一些极限工况下尤其如此;相关的橡胶摩擦实验研究对轮胎力学特性的研究具有重要的参考价值.
Based on a newly developed tire tread rubber friction tester, a simulation friction test method between the tire and the whole vehicle and the ice surface was established, and the instantaneous test method at high slip speed and the continuous The friction test of tire tread block and ice surface under different slip speed, pressure and temperature were carried out and the test results were fitted and analyzed.The results show that as the main component of the tire Rubber exhibits a very specific frictional behavior which does not comply with the Coulomb friction law; the mechanical properties of rubber tires depend to a large extent on the friction properties of the rubber, especially under some extreme conditions; the relevant rubber friction experiment Tire mechanical properties of the study has important reference value.
