A High-Speed Running Test Platform for High-Temperature Superconducting Maglev

Higher speed is the eternal goal of rail transit, and maglev is an important development direction of rail transit in the future. High temperature superconducting (HTS) maglev has the potential for high-speed application because of its non-friction, self-stabilization and no inherent magnetic resistance in the forward direction. Different from the low-speed operation, the HTS maglev system may face new problems in high-speed application. Therefore, it is necessary to study the dynamic response of HTS maglev at high speed. At present, the influence of various factors on HTS maglev system under high-speed operation cannot be accurately considered only by simulations of dynamics software. It is an important research method to build a test platform to measure the dynamic response of HTS maglev system at high speed. By using this method, the test results which are close to the actual application of HTS maglev can be obtained more accurately. In this paper, the HTS maglev high-speed test-platform in Southwest Jiaotong University is introduced and the preliminary results of static and high-speed tests are presented. These results will provide guidance for subsequent tests and provide experience accumulation for the high-speed application of HTS maglev.
