Abstract Tire wear particles are an important non-exhaust contributor of urban particulate matter, which could cause environmental pollution and threaten human health. In this paper, tire-road rolling wear experiments were carried out using a self-made test rig. The size distribution and generation mechanism of wear particles under different non-vehicle operating parameters (treadwear, road roughness and relative humidity) were investigated. The results show that the size of the tire wear particles is an approximately normal distribution in most cases, and tires with good wear resistance produce fewer particles. The quantity of fine particles (

不同非车辆运行参数下轮胎磨损颗粒特性的试验研究

摘要 轮胎磨损颗粒是城市颗粒物的重要非尾气贡献者，会造成环境污染并威胁人类健康。在本文中，使用自制的试验台进行了轮胎-道路滚动磨损实验。研究了不同非车辆运行参数（胎面磨损、路面粗糙度和相对湿度）下磨损颗粒的尺寸分布和生成机制。结果表明，轮胎磨损颗粒的尺寸在大多数情况下近似正态分布，耐磨性能好的轮胎产生的颗粒较少。细颗粒数量（
