冬季新胎与磨耗胎的冰雪路面抓地性能研究

Study on the Grip Performance of Icy and Snowy Roads with New and Wear Tires in Winter

在干冰面、湿冰面和雪面上对不同品牌冬季胎新胎和磨耗胎进行加速、制动试验,研究了在相同路面上磨耗胎相比于新胎的加速、制动性能变化情况,以及同一轮胎在不同冰雪路面路面上的加速、制动性能。试验结果表明:除在干冰面个别磨耗胎抓地性能优于新胎外,其余情况下磨耗胎的抓地性能均较新胎有不同程度的衰减;新胎和磨耗胎的性能表现并没有绝对的一致性,对轮胎新胎的性能测试评价不能代表轮胎全生命周期内的表现。

Acceleration and braking tests on new and wear tires of different brands of winter tires on dry ice,wet ice and snow roads.The change of acceleration and braking performance of wear tires compared to new tires on the same road and the acceleration and braking performance of the same tires on different ice and snow roads are studied.The results show that in addition to the fact that the grip performance of individual wear tires are better than that of new tires on dry ice,wear tires are decreased to some extent compared with that of new tires.There is no absolute consistency between the performance of new and wear tires,and the performance test evaluation of the new tires cannot represent the performance of the whole tires life cycle.
