摘要
为研究轮胎滑水与抗湿滑性能的关联及其影响因素,设计了3种试验方案:对比标准新轮胎和磨损轮胎在水膜厚度1和8 mm的路面上在不同车速区间制动性能的变化,对比不同胎面硬度轮胎在10~30℃下的滑水性能,分析车辆在牵引力控制系统(TCS)打开/关闭状况下滑移率随试验车速的变化。结果表明:当试验车速大于轮胎滑水车速时,轮胎抗湿滑性能较差,受水漂影响严重;当试验车速小于轮胎滑水车速时,轮胎抗湿滑性能较好;随着胎面硬度的增大,轮胎滑水车速呈近似线性增大;在车辆TCS打开状况下,轮胎滑移率可控制在较低数值区间,不会发生完全水漂现象。
To study the correlation between the tire hydroplaning and wet skid resistance performance and its influencing factors,the three experimental schemes were designed:comparing the changes in the braking performance between new standard tires and standard worn tires at different vehicle speed ranges on the roads with the water film thicknesses of 1 and 8 mm,comparing the hydroplaning performance of the tires with different tread hardnesses at 10~30℃,as well as analyzing the variation of the tire slip rate with the test vehicle speed in the traction control system(TCS)on/off states.The results showed that,when the test vehicle speed was greater than the tire hydroplaning vehicle speed,the tire’s wet skid resistance performance was poor and was severely affected by hydroplaning.When the test vehicle speed was smaller than the tire hydroplaning vehicle speed,the tire’s wet skid resistance performance was better.As the hardness of the tread increased,the tire’s hydroplaning vehicle speed increased approximately linearly.When the TCS of the vehicle was turned on,the tire slip rate could be controlled within a smaller numerical range,without complete hydroplaning.
