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。
Maglev vehicle / track system dynamics directly affect the safety, comfort and economy of maglev traffic, and these three properties are important factors that determine their application prospects. As the first part of a series of articles, the most fundamental and crucial issues in the dynamics research of maglev systems are discussed - the magnetic / rail interaction and the stability of maglev systems. At present, significant progress has been made in the theoretical analysis and numerical solution of the two-dimensional force of electromagnet and its dynamic characteristics, and the theoretical analysis and experimental study of three-dimensional magnetic / orbit interaction are the future research directions . The research on the stability of maglev system is from the simplest study on the stability of suspension and the study on the stability of the single-rail / orbit system to the stability of the maglev vehicle / orbit system. The future research is still needed to explore the new method of stability analysis of maglev system, The actual application of the research on the dynamic stability of the maglev train system.
