摘　　要：车辆和导轨的耦合振动问题是影响磁悬浮列车安全性和舒适性的重要问题之一。为解决车辆高速运行时面临的稳定性难题,开发并建设了一套高速磁浮车-轨耦合实验平台。平台围绕常导磁浮车的电磁铁模块进行展开设计,其中轨道模块外接激励器,可以模拟各种速度和不平顺下的轨道条件。控制系统基于实车的控制器、斩波器和传感器进行改造,应用DSPACE快速控制原型技术,实现对嵌入式算法的实时监控和在线修改的功能。建立了柔性轨道多体动力学联合仿真模型,便于快速模拟不同控制算法和力学环境下电磁铁的悬浮稳定性。最后,依托实验平台和联合仿真模型,测试了中低速和高速阶段下电磁铁模块的实际悬浮性能。实验表明本平台具有开展高速车-轨-控制器耦合测试和控制算法快速设计的能力,为高速车-轨耦合振动研究、悬浮控制算法优化提供了可靠的设备基础。The vehicle-rail coupling is one of the most critical issues affecting the safety and comfort of maglev vehicles.A high-speed magnetic levitation vehicle-rail coupling experimental platform is developed and constructed to study the suspension stability at high speed.The structure is designed based on the actual electromagnet module of the maglev vehicle and the rail module,which is connected to an external exciter to simulate various rail conditions at different speeds and irregularities.The control system is modified based on the real maglev controller,chopper and sensors,and the DSPACE rapid control prototype technology is applied to monitor and modify the embedded algorithm online.A corresponding multi-body-dynamic co-simulation model with flex rail is established,which is convenient to quickly simulate the suspension stability under different control algorithms and mechanical environments.Finally,the actual real-time control performances of suspension were tested at low,medium and high speeds.Experiments showed that the platform could carry out high-speed vehicle-rail coupling tests,which provides a reliable equipment basis for the study of the vehicle-rail coupling vibration and optimization of the high-speed control algorithm.
