Abstract

The invention discloses a high-temperature superconducting magnetic suspension structure and a high-temperature superconducting strip magnetic suspension train. The high-temperature superconducting magnetic suspension structure comprises a permanent magnetic rail, a suspension frame and a traction linear motor, wherein the suspension frame is located above the permanent magnetic rail, the bottom of the suspension frame is opposite to a suspension dewar of the permanent magnet rail. The suspension dewar comprises two wedge-shaped blocks, wherein inclined surfaces of the wedge-shaped blocks areopposite, and the inclined surfaces of the wedge-shaped blocks are connected through a plurality of elastic members. The permanent magnetic rail is fixed on a rail bed, the suspension frame is provided with carriages, wherein the carriages are connected with the two wedge-shaped blocks. The traction linear motor is used for driving the suspended frame to move on the traction linear motor.
