摘　　要：针对我国高速铁路出现的轮轨匹配问题,以车-地联动,时-空统一,动、静结合为原则进行轮轨关系现场试验方案设计,根据我国高速铁路轮轨匹配特点,选取京沪、武广、哈大、兰新、贵广、丹大6条高速铁路开展轮轨关系现场试验。自2016年以来,钢轨静态、车轮静态、车轮多边形、道岔动静态、轮轨耦合振动等测试项目相继开展,初步获取了轮轨状态变化与车辆异常振动的影响关系,积累了大量试验数据,为改善和优化现场轮轨关系问题提供了数据支撑,为进一步完善我国高速铁路轮轨关系技术体系奠定了强有力的基础。The field test of wheel-rail interaction is designed to solve the wheel-rail matching problems encountered by HSR operation in China and follows the principle of train-ground coordination, time-space consistency and dynamic-static combination. The field tests were conducted on six high speed railways including Beijing-Shanghai, Wuhan-Guangzhou, Harbin-Dalian, Lanzhou-Xinjiang, Guiyang-Guangzhou and Dandong- Dalian, which cover the wheel-rail matching tbatures of Chinese HSRs. Tests on static state of rail, static state of wheel, polygonal wheel, dynamic/static of turnout, wheel-rail coupled vibration, etc. Have been conducted successively since 2016, based on these tests, the relationship between status change of wheel-rail and vehicle abnormal vibration has been basically controlled, and a mass of data have been acquired, providing a solid foundation for solving field wheel-rail problems and improving wheel-rail technical system of China Railway.
