【Abstract】 High-speed rail has been developed rapidly in China. Fuxing high-speed train is now a proud business card of the country. China’s high-speed train effort faced many challenges including wide-area service and continuous operation at high-speed. Despite these difficulties, China has achieved significant breakthroughs in bogie technology, car body technology, traction and braking technology, and network technology. Advancement in these areas led the creation of progressively superior genealogical of high-speed trains. In the process, a brand new theory on dynamics of coupled system in high-speed railways is gradually established. New system coupling calculation method and the invention of manufacturing technology aided by digital simulation platform are instrumental in the innovative development of China’s high-speed railway system. The establishment of a batch of high-speed train basic research experimental platforms, such as the rolling-vibration test rig of rolling stock with the highest test speed in the world and the pantograph-catenary hybrid simulation test rig which won the Thomas Hawksley Gold Award, plays an irreplaceable role in the optimization of high-speed dynamics performance. The operation tracking tests research of high-speed train for the first time in the world reveals the evolution of the train’s dynamic performance in long-term service, and provides a scientific basis for the revolution of high-speed train dynamics and safety assessment. The digital simulation platform, basic research experimental platform and the service performance research experimental platform are constructed as a full life cycle research system of high-speed train dynamic performance. Its practice and application ensure the fast and safe operation of high-speed trains in China.更多还原
