Self-excited Vibration of Single-Magnet Suspension System: Stability Analysis and Inhibition

摘要

摘要: 为了研究EMS型磁浮列车起浮后与轨道相互耦合发生的自激振动对车辆安全性、舒适性造成的影响,建立了单磁铁悬浮系统的车体-悬浮架-轨道的动力学模型.分析了车-轨系统的稳定性及悬浮控制器和系统各主要参数对振动的影响,提出了系统各参数和稳定性关系的表达式,讨论了运用瞬时最优控制算法抑制车-轨自激振动的具体方法.数值仿真了在3组不同系统参数条件下瞬时最优控制对于自激振动的抑制效果.研究结果表明:车辆结构、悬浮控制器、轨道各主要参数在车-轨自激振动中相互影响;当仿真系统起浮10 s时,悬浮气隙振幅分别减少了59%、62%、5%,轨道振幅分别减少48%、94%、73%,表明了控制方法的有效性.

Abstract: The self-excited vibration occurs due to mutual coupling between EMS maglev vehicles and the track. In order to study its effect on the safety and comfort of vehicles, a vehicle body-suspension frame-track dynamic model for single-magnet suspension systems was established. Using this model, the stability of the vehicle-track system was analyzed together with the influence of the suspension controller and main system parameters on the vibration. Consequently, a relational expression between the system parameters and stability was proposed, and a specific method of using instantaneous optimal control algorithm to inhibit the self-excited vibration of the vehicle-track system was discussed. The inhibiting effect on self-excited vibration of the proposed algorithm was simulated under three groups of different system parameters. The results indicate that the vehicle structure, the suspension controller, and the main parameters of the track would influence each other in the vehicle-track self-excited vibration. At the time of 10 s after the simulation system started, the amplitude of the suspension air gap vibration in the three parameter configurations decreased by 59%, 62%, and 5% respectively; and the amplitude of track vibration decreased by 48%, 94%, and 73% respectively, which demonstrated the effectiveness of the proposed control method.
