Description
A new type of electromagnetic guideway for high temperature superconducting maglev was proposed in this paper. The guideway unit is a fan shaped electromagnet that can generate magnetic field for providing enough levitation and guidance forces. A simple multi-object optimization method was used in order to determine the relative optimal geometrical parameters, so that the electromagnet can have a relative higher energy transfer efficiency. The design model was built in COMSOL Multiphysics and an experimental prototype was made to verify the design feasibility. The levitation and guidance forces were measured by a high precision force-measuring platform. The levitation performances of guideway unit along with different variables were analyzed and compared with the simulation results. Afterward, a simple maglev system was built to test the driving stability in the guideway direction. This system consist an electromagnetic guideway and a train body dewar. The guideway can be assembled in two forms: single track and double track. The comparison between the both forms was discussed and analyzed.
