ABSTRACT When a vehicle brakes, the heat generated by friction will increase the temperature of the tire tread and cause thermal wear, which will reduce the tread’s thickness or destroy the tread pattern’s integrity, thereby affecting the tire friction performance. While existing research primarily focuses on optimizing braking distance under ideal tire slip ratio (SR) through antilock braking systems (ABSs), little attention is given to whether this could lead to potential adverse consequences of increased tire temperature and thermal wear. Moreover, there is a lack of studies examining tire temperature and thermal wear under nonideal SRs. To address this gap, a MATLAB model is developed to simulate tire dynamics and estimate tread temperature across diverse braking scenarios. Results indicate a strong linear relationship between braking distance and tire temperature under ideal SR across different road conditions. ABS is an effective mechanism for reducing tire thermal wear and preserving tire friction performance. Interestingly, at higher SRs, a particular scenario arises wherein braking distance is elongated while tire temperature remains low. Additionally, the study discusses the influence of air convection cooling on tire temperature fluctuations. This study provides insights into the effects of ABS and SR on tire thermal wear.

Temperature Rise of Vehicle Tire at Braking

摘要 当车辆制动时，摩擦产生的热量会增加轮胎胎面温度，导致热磨损，从而减少胎面厚度或破坏胎面花纹的完整性，进而影响轮胎的摩擦性能。现有研究主要集中在通过防抱死制动系统（ABS）优化理想轮胎滑移率（SR）下的制动距离，但较少关注这可能导致轮胎温度升高和热磨损增加的潜在负面后果。此外，关于非理想滑移率下轮胎温度和热磨损的研究也较为缺乏。为填补这一空白，本研究开发了一个MATLAB模型，用于模拟轮胎动力学并估算不同制动场景下的胎面温度。结果表明，在不同道路条件下，理想滑移率下的制动距离与轮胎温度之间存在较强的线性关系。ABS是一种有效的机制，可减少轮胎热磨损并保持轮胎摩擦性能。有趣的是，在较高滑移率下，出现了一种特定情况，即制动距离延长而轮胎温度保持较低。此外，研究还讨论了空气对流冷却对轮胎温度波动的影响。本研究为ABS和滑移率对轮胎热磨损的影响提供了见解。
