Research Progress on the Guideway Switch of High-Speed EMS Maglev System
摘要
Abstract
The guideway switch is the key equipment for the line-changing of trains in high-speed EMS maglev systems,playing a vital role in ensuring operational safety and transportation organization.As high-speed maglev technology advances toward speeds of 600 km/h and beyond,higher requirements are imposed on the guideway switch system.Drawing on research,development,and operational maintenance experience of high-speed EMS maglev switches,this paper elaborates on the technical characteristics of high-speed EMS maglev switches;it summarizes research progress in core technologies such as alignment design,structural performance,mechanical configuration,electrical control,and switching timing.The results indicate that research on high-speed EMS maglev switch systems still faces challenges,including complex structure of the switch system and deep interdisciplinary integration,with reliability-based system design and forward theoretical systems yet to achieve breakthroughs;lagging research on intelligent monitoring and fault prediction technologies,hindering long-term operational safety assurance;inadequate performance evaluation of switch service conditions,with indicator systems and real-time assessment methods yet to be established;limited variety of existing switch types,failing to meet diversification needs for maglev transportation networks;and preliminary research on the mechanism of vehicle-switch coupled vibration mechanisms,requiring in-depth analysis of system dynamic response and ride comfort of the vehicle-switch system across the full speed range.Based on systems engineering theory,key future research directions should include theoretical studies on multi-parameter,multi-objective,and multi-constraint optimization design of switches;intelligent perception systems based on dynamic acquisition and real-time analysis of multi-modal data to establish intelligent maintenance systems;deep learning methods to analyze massive simulation and operational data,identifying key indicators affecting switch performance,and establishing a real-time dynamic performance evaluation system;genealogical research on switches for different application scenarios;and detailed modeling of switch systems,studies on self-excited vibrations and the impact of track irregularities to reveal vehicle-switch dynamic stability mechanisms.关键词
