中文摘要 |
车轨耦合振动现象从磁浮列车诞生起,时至今日都没有解释清楚和彻底解决.如何合理的设计车辆和轨道,抑制车轨耦合振动成为磁浮列车系统研究的热点问题.本文建立了简化的车轨耦合系统数学模型,在单铁悬浮系统稳定性条件的基础上,基于奈奎斯特稳定性理论假设了系统相频曲线的变化规则,得到了车轨耦合系统稳定的充分性条件.文末最后证明假设是成立的,计算简化了系统稳定条件式,并以数值计算的方法验证了该稳定性条件的正确性. |
英文摘要 |
Since the emergence of the maglev train, the vehicle-guideway interaction vibration hasn't been well explored and settled.How to design the vehicle and guideway feasibly to attenuate the coupling vibration is a hot topic in the maglev train engineering.Firstly,the simplified vehicle-guideway coupling system is modeled in the paper.Based on the stable condition of single magnet levitation system and Nyquist stable theory,a hypothesis is then brought out to describe the phase diagram,and a sufficient condition is also induced to ensure system stability.Subsequently,the hypothesis is proved and the sufficient condition is simplified.Finally,the result is validated by digital evaluations. |
