| 摘 要： | 以常导磁浮车辆的悬浮导向基本单元为对象，对采用两级串联悬浮控制的单磁铁悬浮系统进行悬浮刚度和阻尼特性的理论与数值分析．分析结果表明：电磁悬浮刚度与间隙反馈系数成正比，悬浮阻尼与间隙变化速率反馈控制系数成正比；车体二系悬挂频率、轨道基频和控制系统特征频率任意两者互相接近时，容易发生车轨共振．

| Abstract: | The suspension stiffness and damping of an actively controlled electromagnetic suspension system were analyzed theoretically and numerically. The suspension unit consisting of single magnet and series suspension controller was taken as the object for analysis. The analytical results show that the suspension stiffness is positively proportional to the feedback coefficient of airgap and the suspension damping is positively proportional to the airgap derivative. Resonance may occur if any two of the characteristic frequencies of the secondary suspension, the guideway and the control system are close to each other. |
