摘要

车轮磨耗直接影响车辆性能和车轮使用寿命,是高速动车组设计的核心技术,由于影响车辆磨耗的因素复杂多变,目前通过仿真和台架试验尚不能准确预测出高速列车车轮的磨耗特征。通过开展大量高速动车组车轮磨耗线路跟踪测试,从镟修周期、运行速度、气候条件、线路状态等多角度总结分析动车组运行环境对车轮磨耗的影响及其演化规律;针对实际运用中出现的轮轨匹配不良问题,设计了新型高速动车组车轮踏面,使其线路适应性更强,并批量应用在我国自主设计的中国标准动车组上,运用效果良好。
        Wheel wear directly influences vehicle performance and wheel service life and is regarded as a core technical issue during high speed EMU design. Due to complexity and variability of factors that result to wheel wear, it is hard to accurately predict the features of worn high speed train wheels via simulation or bench test. Therefore, a lot of tracking tests for high speed EMU wheel wear on lines have been conducted. From different perspectives, including lathing cycle, operation speed, climate and track status, the role played by EMU operation environment in wheel wear and its rules have been analyzed; to cope with the bad wheel-rail match in application, a new type of wheel tread for high speed EMU is developed. It is more adaptable to different track status and has been widely applied on China Standard EMU trains with favorable application feedbacks.
