摘要
磁浮车辆/轨道系统动力学问题直接影响磁浮交通的安全性、舒适性和经济性,而这三个性能则是决定其应用前景的重要因素。作为系列文章的第一部分,论述了磁浮系统动力学研究中最基本和最关键的问题——磁/轨相互作用及磁浮系统稳定性。关于磁/轨相互作用研究,目前在电磁铁二维受力理论分析、数值求解及其动态特性研究方面取得了显著的进展,而三维磁/轨作用理论分析与试验研究是其未来的研究方向。磁浮系统稳定性研究由单纯的悬浮稳定性研究、单铁/轨道系统稳定性研究逐步进入磁浮车辆/轨道系统稳定性研究,将来的研究仍需探索新的磁浮系统稳定性分析方法,并结合工程实际开展磁浮列车系统动力稳定性应用研究。
Dynamic responses of maglev vehicle/guideway system have important influence on running safety, ride comfort and system costs, which are crucial factors for maglev train commercial application. As the first part of the series paper, the essential issue of maglev vehicle/guideway system dynamics is discussed, including the magnet/rail interaction and the dynamic stability. Remarkable advance has been made on the 2-diemesional theoretical analysis and dynamic simulation of magnet/rail interaction. It is necessary to carry out theoretical analyses and experimental studies on the 3-diemensional magnet/rail interaction in the future. The magnet suspension stability, single magnet/guideway system stability and dynamic stability of simple maglev vehicle/guideway system had been investigated in the past thirty years. In order to meet the demand of developing the commercial maglev system, it is suggested to investigate as soon as possible the dynamic stability of the full-scale maglev vehicle/guideway system.
