Levitation performance of magnetically suspended high speed trains

Analyses have been made of the design parameters which affect the magnetic lift and drag forces on the magnetically suspended very high speed train models of practical interest. In the suspension systems investigated here, the superconducting magnets are installed in the train and the roadbed is equipped with normal-conducting coils. As a result of this investigation, an improved suspension system is proposed, which consists of "ladder-type conductor" in the roadbed. This new system is investigated theoretically.
