A Manned Hybrid Maglev Vehicle Applying Permanent Magnetic Levitation (PML) and Superconducting Magnetic Levitation (SML)

Abstract

To enhance maglev competitiveness in passive stability and simple structure, a manned hybrid maglev vehicle applying permanent magnetic levitation (PML) and superconducting magnetic levitation (SML) was developed. The vehicle is mainly composed of a maglev frame, a PML part, and an SML part. The maglev frame was employed to connect the PML and SML parts. Based on the magnetic rail of our high temperature superconducting maglev test line of the “Super-Maglev,” the onboard levitation components are bespoke to match the magnetic rails. The PML part is assembled to the maglev frame by vertical linear sliders, and is able to move freely in the vertical direction for appropriate heavy load. The driving method is linear induction motor whose primaries are installed between two rails, interacting with the induction plate mounted on the SML part. The rated load is designed as 375 kg and achieved for one passenger at 15 mm field cooling height. Measurements of its mechanical property were performed under static loads. Results display that the manned hybrid maglev vehicle possesses good advantages of load ability and passive stability at the same time. The work explores a new feasible combination of the PML and the SML for maglev applications.
