对超导磁悬浮转向架进行了数值模拟研究。该系统是基于侧壁电动悬架（EDS），保持气隙长度在约10厘米。虽然EDS系统具有无需主动控制即可稳定悬浮的优点，但数值仿真结果表明，悬浮系统的阻尼因子较小。因此，提出了主动阻尼线圈系统。在转向架超导线圈前安装铜线圈作为阻尼系统。我们已经设计了阻尼线圈，以增加对垂直振荡的阻尼。在考虑供电限制的情况下，对转向架进行了运行仿真。主动阻尼线圈系统减小了振动的幅值，增大了阻尼因子，数值分析证实了其效果。
Numerical simulation of the superconducting magnetically levitated bogie (JR Maglev) has been studied. This system, which is based on the side wall electrodynamic suspension (EDS), keeps the airgap length at about 10 cm. Although the EDS system has the advantage of stable levitation without active control, the result of the numerical simulation shows that the damping factor of the levitation system is small. So the active damper coil system has been proposed. Copper coil is installed in front of the superconducting coil on the bogie as damper system. We have designed damper coils to increase the damping against vertical oscillation. Running simulation of the bogie considering the limitation of the power supply is undertaken. The active damper coil system decreases amplitude of the oscillation and damping factor becomes large, and its effect is confirmed by numerical analysis.
