摘　　要：基于电化学原理和无线通信技术,研制了高速列车材料腐蚀状态智能监控系统,分别在海南文昌、湖北武汉、山东青岛三地的环境腐蚀试验站及京广高铁在役高速动车组上进行了部署,并连续开展了6个月以上的腐蚀数据在线采集及分析,掌握了动车组车体铝合金材料及涂层6个月的腐蚀老化规律,为预测车辆结构材料的腐蚀风险、评估涂层的寿命衰减,加强动车组全生命周期安全管理提供了重要的数据支撑。With the expansion of high-speed train operation area and the extension of service duration, corrosion has become an important factor threatening the safety and reliability of trains. Based on electrochemical principle and 4 G wireless communication technology, a novel intelligent corrosion monitoring system for structural materials of high-speed train was developed. It was installed on a high-speed train traveling between Beijing and Guangzhou, as well as in three out-door exposure test stations in Wenchang, Wuhan, and Qingdao as a menas to perform comparatively examination of material corrosion. The 6-month continuous corrosion data of an Al-alloy and protective coating of high-speed train carbody, as well as those in the above test stations was collected and analyzed. The data provides important support for predicting the corrosion risk of vehicle structural materials, which is in favor of evaluating the life attenuation of coating and strengthening the safety management of the whole life cycle of high-speed train.
