Numerical running simulation of the superconducting magnetically levitated system (JR Maglev system) has been undertaken. In this system, the interaction between the propulsion and levitation system is very large. Thus, it is important to reduce the oscillation of the bogie caused by the various disturbance. The damping of the system is shown to be small. So the active damper coil system is proposed to increase the damping between the bogie and the levitation coils on the ground. The effect of the active damper coil is calculated using the running simulation program. From the calculated results, the active damper coil system shows the large effect to decrease the vertical oscillation of the bogie when the voltage in proportion to the acceleration of the vertical oscillation is applied on the damper coils.
